For every key we press, we keep a map of its state each cycle (for 8 cycles).
When the key is released, we color it white if we had more than two state
changes (ie, chatter), otherwise we turn it blue (all is well).

Refactor the momentary layer handling part of `handleKeymapKeyswitchEvent`.
Instead of a bunch of ifs that are increasingly hard to follow, use a switch
based on the target layer, and branch out depending on `keyState` from there.
Makes it easier to follow what happens.

If we have two keys on our keymap that momentarily go to the same layer (which
is the case for the factory firmware), we hold both, and release one, we want
the layer to remain active still.
To this effect, in `handleKeymapKeyswitchEvent` we will handle the case when a
momentary layer key is pressed, but not toggled on (that is, it is held): if it
is not a next/previous switch, we re-activate the layer if it wasn't on.
This fixes#154, thanks to @ToyKeeper for the report.

With the new implementation, there are two lookup functions, because we have two
caches, and different parts of the firmware will want to use either this or
that (or perhaps both, in rare cases).
First of all, we use caches because looking up a key through all the layers
is costy, and the cost increases dramatically the more layers we have.
Then, we have the `effectiveKeymapCache`, because to have layer behaviours
we want, that is, if you hold a key on a layer, release the layer key but
continue holding the other, we want for the layered keycode to continue
repeating. At the same time, we want other keys to not be affected by the
now-turned-off layer. So we update the keycode in the cache on-demand, when
the key is pressed or released. (see the top of `handleKeyswitchEvent`).
On the other hand, we also have plugins that scan the whole keymap, and do
things based on that information, such as highlighting keys that changed
between layers. These need to be able to look at a state of where the
keymap *should* be, not necessarily where it is. The `effectiveKeymapCache`
is not useful here. So we use a `keymapCache` which we update whenever
layers change (see `Layer.on` and `Layer.off`), and it updates the cache to
show how the keymap should look, without the `effectiveKeymapCache`-induced
behaviour.
Thus, if we are curious about what a given key will do, use `lookup`. If we
are curious what the active layer state describes the key as, use
`lookupUncached`.

Only update the keymap cache if the layer state changed for real. If we turn a
layer that was already on, on again, we do not need to update. Same for turning
them off.
This results in a tiny speedup if we have code that calls `Layer.on()` or
`Layer.off()` often.

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.

To find layer keys and layer keys only, we need to make sure that `key.flags`
has only these two bits set, and none of the others. Otherwise it may light up
keys as if they were layer keys, while they aren't, because they happen to have
`SYNTHETIC` and `SWITCH_TO_KEYMAP` set, `RESERVED` unset, but have other flags
that make the event handler loop treat them properly. Mouse keys are one such
thing.
Thanks to @ToyKeeper for reporting the issue!

If the `RESERVED` bit is set, that means the key is outside of the control of
the core firmware, and as such, can't be a normal layer key. As it happens,
`OSM(LeftControl)` (and other OSM keys) triggered this branch of code, and
resulted in one-shot modifiers getting highlighted too.
Thanks to @ToyKeeper for reporting the problem, and providing reproduction
steps.

We are trying to migrate to the former, so while I'm here, do so in this plugin,
so we can deprecate and remove `loop_hook_use` sooner.

Make it clear that layer keys are considered modifiers by the plugin.
While in that area, use `Kaleidoscope.use` instead of the now deprecated
`USE_PLUGINS` macro.

The goal is to have a single `if` for checking if we should highlight a key, so
that we can later have an `else if` branch to highlight non-traditional
modifiers.
Signed-off-by: Gergely Nagy <algernon@madhouse-project.org>
To make it easier to extend the plugin, to teach it to highlight keys other than
the traditional modifiers, lift the code that checks for a modifier into its own
function.
No functional change, just refactoring.

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.

Uses mickeys (1/16th subpixel units) now instead of pixels. Much smoother!
Added "speedLimit" config var to set maximum cursor speed.
Ensured default values are sane.
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.
