When we change layers, we want to update the key cache for the whole keyboard,
so that LED modes and other things that depend on all keys being up-to-date will
work as expected.
Do the same at `Kaleidoscope.setup` time, so we start with a good state too.
This fixeskeyboardio/Kaleidoscope-Numlock#7.

It may happen that we get passed an UNKNOWN_KEYSWITCH_LOCATION, which will
always be out of bounds. Lets not corrupt random memory when in this situation,
but instead, return quickly.

For some odd reason, initializing it there crashes the firmware early on. Until
I figure out how to fix this, lets default to an implicit false.

Switch from the masking behaviour to repeating the symbol the key had when first
pressed.
This - along with the previous changes - fixes#158.

Instead of storing the layer for each key, store the keycode, so that lookups
are considerably faster (one array lookup instead of two). This saves us almost
a full millisecond per scan cycle. Furthermore, inline `Layer_.lookup`, saving
us even more time.

This changes how key caching & lookup works: instead of updating the whole key
cache whenever we change the layer state, we update each key before they are
pressed or released. This allows us to have two different ways in which layers
can work:
- Keys still held when releasing the layer key will be masked out until they are
released. (This is the current behaviour)
- Keys held will repeat the keycode they had when they toggled on, even if the
layer key gets released prior to this other key, while other keys will not be
affected.
One can toggle between the two modes by setting
`Kaleidoscope.repeat_first_press` to `true` (second behaviour) or `false` (first
behaviour).
For now, the default behaviour is left unchanged.

Since we have a nice keydata_t union, use that, to convey it even more clearly
that we are mimicking the hand states in a way.

By not using 32-bit ints, we already saved a noticeable amount of space. If we
follow the `*HandState` bit layout more closely, we can shave off some more
bytes too.

Dealing with 32-bit numbers on Atmega32u4 is very costy, so lets try to avoid
that, and use four 8-bit uints instead. This save us about a hundred bytes of
progmem.

The `SCANBIT` macro was not using `row` and `col` properly: if either was
anything else than a number (such as `col - 8`), the macro did not expand them
correctly, preserving operator precedence. As such, the right-hand side SCANBITs
were broken when used with masking, because the masking code uses `SCANBIT(row,
col - 8)`, and the `(7 - col)` part would expand to `(7 - col - 8)` which is
very different than `(7 - (col - 8))`.
This patch addresses the issue.

When a masked key is released, instead of unmasking it and returning, unmask it
and let the event through. This fixeskeyboardio/Kaleidoscope-OneShot#10.

The goal is to ignore key events from still-held keys in a situation where we
just turned a layer off. Thus, if one holds a momentary layer key, then presses
and holds another key, releases the layer key, we want to ignore the other held
keys until they are released.
This is accomplished by masking all held keys when a momentary layer has been
turned off, and ignoring all masked key events in `handleKeyswitchEvent` until
they are released, when we unmask them.
This should address #150, but requires
keyboardio/Kaleidoscope-Hardware-Model01#9.

There are situations when one wants to ignore key events for a while, and mask
them out. These newly introduced functions help do that.
They are in the Hardware plugin, because this is where it is most efficient to
implement the masks: the hardware library knows how many bits it needs, and how
best to represent the masks. We use a 32-bit bitmap here, other keyboards may
use a different size, or an entirely different approach too.
This is one part of the fix to address keyboardio/Kaleidoscope#150.

rather than send key down events for a while before sending a key
release event as we did with the old scheme, this sends the events
paired together as "one shot". This is closer to the spec and what OSX
needs to accept these events
