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
intended if the board we're running on implements RGB order differently.

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.

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.

We should be using a different variant of the `default_layer()` method to query
the default layer instead of abusing 0xff as a special valie.

Add `REDIAL` to `kaleidoscope::ranges`, so the plugin can define `Key_Redial`
itself, and won't need `Redial.key` to be set in the user sketch either. This is
a breaking change, but one that's easy to upgrade to, hence no effort was made
to make it at least partially backwards-compatible.
Fixes#519.

When selecting a new default layer via Focus, we should be moving there too,
because there may be no other way to switch to the new layer, and having to
reboot the keyboard for changes to take effect is not our desired behaviour.

When sending `Key`s, there's no need for an extra separator, because
`send(key.raw)` will send one anyway. Not sending one results in 10 bytes less
PROGMEM used, and plenty of bytes less spent over the wire.

When we use `lookup()`, we're looking up from the cache, not from the active
layer. If the cache gets updated later than we're called, we won't notice. So do
an explicit lookup.
