Sometimes we would like to know the highest active layer, which is available in
the `highestLayer` private variable, and via `.top()` too. We do not want to
make `highestLayer` public, because we want to be the only ones changing it. And
while `top()` gets us roughly the same information, it does so at a cost. For a
lot of purposes, the cached `highestLayer` would be perfectly adequate.
The new `Layer.highest()` accessor does just this.

There were a number of issues with the model we had before, namely that plugins
that changed LED colors outside of LED modes had no way to signal "go back to
whatever color this key was". To this end, the `LEDMode.refreshAt` method is
introduced, which these plugins can call to tell the mode to update a given key.
As part of this, the API was redesigned, with code that is common between all
LED modes moving to the base class, among other things, much better names, and a
flow of control that is easier to follow.
In the new setup, there are four methods a LED mode can implement:
- `setup()` to do boot-time initialization (registering hooks, etc).
- `onActivate()` called every time the mode is activated.
- `update()` called each cycle.
- `refreshAt()` may be called by other plugins to refresh a particular key.
All of these are protected methods, to be called via `LEDControl` only.
Much of the new API design was done by @cdisselkoen, huge thanks for his work!
Fixes#9.

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.
