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.

Now that we're using a struct with descriptive member names, drop the helper
macros that made using bitfield manipulation readable. The code's readable
without them by now.

On AVR8, 16-bit bit-operations are expensive. Switch from using 4(!) 16-bit
bitfields to using a 16-element array of a carefully constructed struct.
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.

The google style allows all_lowercase names for things that are like accessors and mutators, but does not require it. I find that in our codebase, it just makes things look inconsistent

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.

Counting cycles is an incredibly unreliable way of timing animations. Use timers
instead.

When not using the `CRGB()` macro, colors may end up being different than

Since `Focus.send()` does not send a newline implicitly, we should do so
explicitly. Introduce `Focus.NEWLINE` to help with this, and not have many
copies of `'\n'` lying around.

The KBD4x has a set of WS2812 LEDs, which are very picky about timing. To make
them happy (even though we do not use them yet), we need to disable clock
division at startup.

We deprecated a number of interfaces, which were scheduled to be removed on the
14th of January. Lets remove them now.
Incidentally, we had a number of places where we used the old names internally
too, and this has been corrected as well now.

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.
Fixes#529.

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.
