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.

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.

Given a `row`/`col` coordinate, this new function returns the index of the LED
under that key. To be used with the `led_set_crgb_at(i, crgb)` function.

Drop the `load_primary_layer` and `save_primary_layer` methods, because
`save_primary_layer` is not used anywhere, and as such, the whole thing is
pointless at this time.
Furthermore, if we want to allow plugins to implement EEPROM storage, then its
best if we leave the default layer save/load to the plugins too.

To further improve the LED performance, sync only when there is a change. We do
this by tracking when change happens, assuming everyone uses the provided
accessors.
While we do a bit of extra work each cycle to do the tracking, that pales in
comparison to what we gain by not having to transfer data needlessly.

The `CRGB` macro takes rgb values as arguments, in this order, and creates a
`cRGB` instance with the components rearranged to fit the ordering of the
hardware (in the case of the Model01, bgr).
