When there are no state changes, and no keys pressed on a row, instead of
iterating through a byte bit-by-bit, just fire idle events without checking the
bits. In all other cases, do the bit-walking like we did before.
The reason this is useful is because bit-walking is costly, and slow. If we can
avoid that, we win quite a lot of performance. Since rows being idle is the most
common case on a keyboard, this is a huge net win. Even in the worst case, where
no rows are idle, this is just one byte comparison and a branch slower than our
previous implementation.
As part of this optimization, `actOnHalfRow` was lifted out into its own
function, to reduce code duplication.
Many thanks to @gedankenexperimenter for the original idea!

Allow user to specify custom boot greeting key by Key_* or by specific row and column. Add ability to define custom duration of boot greet breathing effect, and add ability to change color hue of breathing effect. Finally, rework logic that happens when plugin is loaded to allow all user custom settings to be properly read and applied as expected.
add hue to the header
Updated readme to support new features
astyle + change to allow custom settings
There are a number of false-positives, where ShellCheck warns about behaviour we
do want, or are otherwise intentional.

If the user has missed the step about setting up their account
with the right group membership, they would get a cryptic failure
from stty, so catch this and explain the problem.
This should never happen, but could if something goes badly wrong
in the device detection code, e.g. someone changing it in a way
which caused extra output on STDOUT.

says:
It should be enough to set ID_MM_DEVICE_IGNORE:="1" but it seems many
versions of modem manager have a bug which makes them ignore that value.
Setting ID_MM_CANDIDATE:="0" has the same effect but is an "internal
implementation detail" of modem manager.
so set both to be safe. Also use := rather than =, in order to prevent
any later rules from overriding the settings.
In `hexToKeysWithNumpad`, have a default case, a pointless one, because we never
take that branch, but it silences a warning.

This avoids the OS being stuck with Numlock on, which leaves the LED on
if other keyboard are attached, and breaks FVWM.
See keyboardio/Model01-Firmware#42
Further testing suggests that macOS unconditionally replaces the final character with a
`1` (I tested with `kbio02` as the device short name, which became the "Serial Number"
`CDkbio02`, and it got changed to `CDkbio01` in the filename). This change will try
looking for any file that matches the serial number with the final character replaced with
"1" (not just if that charater is "E"). I also added some comments that might help update
the script in the future if the OS changes behaviour.
This restricts the data type of the enum to uint16_t, so if anyone ever adds enough values
to it to overflow the 16 bits that are available in the Key structure, even if they do it
without an assignment (e.g. `TOO_BIG_ENUM = 0x10000`), it will result in a compilation
error instead of runtime errors.
Several people have reported difficulty flashing firmware on macOS High Sierra because the
device port filename doesn't match the serial number from system_profiler. In particular,
system_profiler would return a string ending in `E` whereas the device filename would have
a `1`. This change adds a check for that filename explictily.
I also corrected the location_id fallback (the substring should have been just 3
characters long, not 4), and it works properly on my system if I make the device shortname
7 characters long, and the filename reverts to using the location id instead.
Last, I added one more check, simply listing the filenames, and searching for a match for
the string `kbio01`, which should be present (although in one case, it wasn't).
It's easier for most people to interpret numbers in decimal than hexadecimal; adding this
option to avr-nm prints out the sizes in the size_map in a more intuitive format.
