…k#8674)

* Invert UC_MOD/UC_RMOD direction when Shift is held

Also use MOD_MASK_SHIFT in process_rgb.c

* Allow audio to be played for UC_MOD, UC_RMOD keycodes as well

* Fix signedness bug in reverse input mode cycling

* Misc formatting in process_unicode_common.c

* Address clang-format issues

* Make decode_utf8 helper function file-local (static)
