Reduce PROGMEM usage for sendstring LUT (#8109)
* Reduce PROGMEM usage for keycode map
Bit-pack the keycode bool array to gain back a small amount of flash space.
The trade-off is an increase in runtime instructions when running macros.
It does make the code a bit harder to read, as well as maintain.
For configs that use send_string() et al, it saves ~100 bytes.
* Switch to macro and common definition
Rewrite the array declarations so both the unpacked (original) and
packed LUT arrays can use the same value definitions. This is done by
defining a macro that "knows what to do".
This makes the code much easier to read and maintain.
* Fix macro typos and improve perf
Pack the bits in a more efficient order for extraction.
And also fix the copy/paste error in the macro...
* Switch fully to packed LUT
Some minor reformatting.
Compile tested all sendstring_xyz.h to make sure they were converted
properly. Also checked that an unconverted version would generate a
compile error.
* Apply whitespace suggestions from code review
