This is a complete rewrite of OneShot, based on the keymap cache
redesign. This allows OneShot to abort the release of a key, causing
its cache entry to stay valid if it's in an active state after the key
is released, allowing us to fix#896 (double-tapping a layer shift key
doesn't make it sticky).
Instead of tracking `Key` values, OneShot now uses two bitfields of
the keyboard in order to track the OneShot state of every valid
`KeyAddr` independently. This could enable the creation of a OneShot
"meta" key, which could be used as a way to make any key on the
keyboard exhibit OneShot behaviour.
The new OneShot plugin immediately replaces the OneShot `Key` value
with its corresponding "normal" key, and activates its OneShot status
by setting one bit in one of the bitfields.
Also included:
* A rewrite of LED-ActiveModColor that makes it compatible
with the new OneShot, and add support for Qukeys
* Updates to Escape-OneShot for compatibility and efficiency
* Minor updates to Qukeys
* The new KeyAddrBitfield class
KeyAddrBitfield:
This class can be used to represent a binary state of the physical key
addresses on the keyboard. For example, ActiveModColor can use to to
mark all the keys which should be highlighted at any given time. It
includes a very efficient iterator, which returns only `KeyAddr`
values corresponding to bits that are set in the bitfield. It checks a
whole byte at a time before examining individual bits, so if most bits
are unset most of the time, it's very fast, and suitable for use in
hooks that get called every cycle.
ActiveModColor:
This makes LED-ActiveModColor compatible with Qukeys, and removes its
16-modifier limit, while simultaneously reducing it's footprint in RAM
and eliminating a potential buffer overrun bug where it could have
written past the end of its state array.
