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 Co-Authored-By: Ryan <fauxpark@gmail.com> Co-authored-by: Ryan <fauxpark@gmail.com>
