The LED-Stalker plugin was looping through its table of `step` values (one for each key)
on every call to `update()`, and calling `compute()` on every value there, but those table
entries were only updated once every 50ms (by default), resulting in a lot of repeated
computation. This resulted in the mean idle cycle time increasing from 565µs to 1317µs on
the Model01 with an (almost) unmodified standard sketch.
This change moves the check for the timeout before the loop through the `step` values, and
aborts processing there if not enough time has elapsed. The resulting mean idle cycle time
becomes 577µs -- an almost negligible increase. It also reduces the PROGMEM footprint by
44 bytes.

This commit silences a warning due to an undefined variable.
A first attemt to locally supress the warning using compiler pragmas was
unsuccessfull due to a compiler bug in all gcc versions. This bug
in all gcc versions below 6.1 makes local diagnostics suppression useless.
As future versions of Arduino will ship with later versions of gcc
from a certain point on, the supplied warning suppression macros will become useful
to avoid the necessity to set global compiler flags like -Wno... and to
enable more precise warning suppression.
The new header file comes with an example that explains how to use
the suppression mechanism.

On AVR8, 16-bit bit-operations are expensive. Switch from using 3 16-bit
bitfields to using a 16-element array of a carefully constructed struct.
This saves us almost 300 bytes of PROGMEM at the cost of 10 bytes of memory.

I tried to be smart and use `sizeof()` instead of hard-coding the array size,
but I used it wrong, and we iterated to 32 instead of 16, overflowing the array
and looking at parts of the memory we had no business looking at. This resulted
in `isPressed()` and `isSticky()` always being true.
Instead of trying to be clever, use `OneShot::ONESHOT_KEY_COUNT` throughout,
which is a constexpr defined at 16, the number of oneshot keys we have.
Fixes#572.

In `beforeReportingState()` and `afterEachCycle()` we used to return early if no
OneShots were active. This was easy to do when we were using a bitfield, we'd
just tested for non-zero. Since we're using an array now, this check is more
expensive, and the extra work negates any benefit of returning early.
For this reason, these early returns are removed.

On AVR8, 16-bit bit-operations are expensive. Switch from using 4(!) 16-bit

This saves us about 242 PROGMEM at the cost of 8 bytes of memory, and a tiny
performance hit.

We want to be able to notice when the layout of the EEPROM *settings*
changed (which the CRC does not cover). For this reason, we're repurposing the
existing version setting, which wasn't widely used: it is now internal.
We use the version to determine whether the EEPROM has been written to yet, or
if it is uninitialized. This helps us make sure we're starting up with sensible
defaults.
Fixes#559, and fixes#558.

Previously we requested a slice in `onSetup()`, but this had a major,
problematic implication: if we went from a sketch with `EEPROM-Keymap`, but
withot `LED-Palette-Theme` enabled to one with it, the EEPROM layout was not
compatible, no matter what the order of plugins in `KALEIDOSCOPE_INIT_PLUGINS`
were. This happened because `EEPROM-Keymap` requested space *after* `onSetup()`
already ran.
To fix this issue, request a slice in `.reserveThemes`, only if we didn't
request a slice yet. This way the EEPROM layout is decided by the order of
initialization in `setup()`, and we do not sneakily steal a slice in
`onSetup()`.
This is required to address keyboardio/Chrysalis#270.

Instead of having a single `keymap.map` Focus command that tries to be smart
about what layers it presents, we should have two separate commands: one to
query the defaults (PROGMEM), and one to get/set the custom keymap (EEPROM).
This makes `keymap.map` and `keymap.roLayers` obsolete, and they're now removed.
Furthermore, having to specify whether the EEPROM keymap extends the built-in
one or not proved to be unflexible. So we re-purposed the highest bit of the
first EEPROM byte, to signal whether we should use EEPROM layers only or not.

We want to give the hardware enough time to give us a stable read of the pins.
If we unroll the loop, we will not have that. In practice, this leads to entire
rows or columns behaving erratically.
To fix that, we tell the compiler not to unroll loops in the `readCols()`
method (it's free to unroll them elsewhere). This makes the function a tiny bit
slower, but gives us a stable read.

EEPROM defaults to `0xff` when uninitialized, which means we'd start off with a
bright white palette. That's a problem, because it draws a lot of power,
especially when all keys are lit bright. For this reason, flip the bits when
reading or storing palette colors, so the default `0xff` becomes `0x00`, black.

Brace-initialization has issues, especially with newer compilers that try to do
more, and better optimizations. To allow them to do these, we should be striving
for better type safety. For this reason, use the new Key() constructors to
initialize the various key defines. This gives the compiler much better hints.
The code becomes much more readable too.
This is fully backwards compatible, we're not removing any existing interface,
just using a newly introduced one. The old ways still work. They might produce
warnings with newer compilers, but they did so before anyway.

We need to guard the `k` argument, place it within parens, to make sure it is
treated as a single argument, even if it expands to something that would be
ambigous. This is required, because most - if not all - keys are defined as a
list casted to `Key`, which the pre-processor would misinterpret without the
extra parens.

To make it easier to create custom shortcuts, that do not interfere with system
ones, an old trick is to use many modifiers. To make this easier, Ctrl+Shift+Alt
is commonly abbreviated as "Meh", while Ctrl+Shift+Alt+GUI is often called
"Hyper". To support this, we offer the `Key_Meh` and `Key_Hyper` aliases, along
with `MEH(k)` and `HYPER(k)` to go with them.
