Drashna Jaelre d41961c9ed [Keymap] Drashna's Feature madness (#6128)
* Fix my Tap Dance issues after I broke them

* Cleanup and organization of userspace documentation

As well as some additional cleanup of functions due to review of documentation.

* Enable Tapdance on Glow and remove more animations

* Revert to Eager PR debouncing

* Add better check for startup animation

* Move where RGB Matrix defines are listed

* Limit RGB Matrix max val

* Update keyboard for Iris Rev 3 conflicts

* Enable encoder support on planck ez

* Remove is_master check from corne\'s OLED code

* Overhaul OLED screens for my Corne

* One last removal

* Show RGB valu On both sides

* Updates for OLED display info

* Fix compile issues for rgb config

* Disabled Space Cadet for all drashna keymaps

* Fix OLED Screen configs

* Minor OLED Tweaks

* Revert some Iris changes

* Fix song include

* Handle MAKE macro for the Corne boards better

* Add super hacky-hack for eeconfig initialization

* Add audio support for Fractal since Elite Cs support it

* Add defines for keycode steps

* Add White layout

* Update Corne RGB info

* Add fun effects to layer indication for RGB Matrix enabled boards

* Use proper define for product name detection

* Update formatting

* Use custom timeout mechanism for OLED timeout

* Fix up OLED screen HSV code for new HSV structure

* Better handle turning off RGB Matrix when sleeping

* Disable MultiSplash Animation

* Change Iris back to using serial

* Why was RGB disabled?!?!?!

* Limit val in rgb_matrix_layer_helper function

# Layer Indication Code
At least for RGB Light, the `layer_state_set` function is used to detect the current highest layer, and change the underglow based on that layer.
This works for both the regular layers, and for the default layers, too.
I use the sethsv variants of the commands, so that different modes can be used, as well.
RGB Matrix uses a custom, per board implementation, at the moment.
# RGB Light Startup Animation
On startup, if enabled, the board will cycle through the entire hue wheel, starting and ending on the default layer color.
```c
void keyboard_post_init_rgb(void) {
#if defined(RGBLIGHT_ENABLE) && defined(RGBLIGHT_STARTUP_ANIMATION)
if (userspace_config.rgb_layer_change) { rgblight_enable_noeeprom(); }
if (rgblight_config.enable) {
layer_state_set_user(layer_state);
uint16_t old_hue = rgblight_config.hue;
rgblight_mode_noeeprom(RGBLIGHT_MODE_STATIC_LIGHT);
for (uint16_t i = 255; i > 0; i--) {
rgblight_sethsv_noeeprom( ( i + old_hue) % 255, 255, 255);
matrix_scan();
wait_ms(10);
}
}
#endif
layer_state_set_user(layer_state);
}
```
This could probably benefit from some cleanup and better handling.
# RGB Light Twinkling
This enables random twinkling of the LEDs when typing.
# RGB Light Mod Indicators
Allows feedback of which mods (oneshot or otherwise) are enabled.
