* Enable link-time optimization
* Make RGB static gradient ranges shorter
* Shift Quefrency media keys to the right
* Shift KBD67 media keys to the right
* Move some 60% keys from function to adjust layer
* Set "extra" Lily58 keys to browser back/forward
* Remove Instant60 EEPROM hack after #6968
* Remove unnecessary bits from macropad keymaps
* Update KLE images
* Turn off more unnecessary features by default
* Double TAP_CODE_DELAY due to more media key issues
Even with this change, some of the rotary encoder turns on my BDN9's
volume knob still seem to get dropped. It's possible there's something
wrong with the encoder itself. (Maybe the TAP_CODE_DELAY actually causes
QMK to miss an encoder turn? Unclear.) The other knob (backlight
brightness) works fine, FWIW....
* Restructure userspace config.h a bit
* Hack around Instant60 Via EEPROM conflict
Remove this when #6589 is fixed for Via boards.
* Add backlight breathing and (EEPROM) reset to BDN9
* Add keymap for 9-Key macropad
