[Docs] RGB Animation documentation on reducing memory footprint (#5813)
* Improve Animation docs with example - example to reduce flash footprint of animations using RGBLIGHT_EFFECT_ defines * Re-order the effects list * Update docs/feature_rgblight.md Co-Authored-By: yanfali <yanfali@gmail.com> * Update docs/feature_rgblight.md Co-Authored-By: yanfali <yanfali@gmail.com> * Update docs/feature_rgblight.md Co-Authored-By: yanfali <yanfali@gmail.com> * Introduce line breaks * Add title for animation speed section * Organize Animation Defines Into Groups * Use the RGB EFFECT recommended by mtei in docs - has the most modes, and STATIC_LIGHT can't really be disabled. * Use more accurate titles for effects and animation - accidentally put a toggle in settings

### Effect and Animation Toggles
|
||||
|
||||
Use these defines to add or remove animations from the firmware. When you are running low on flash space, it can be helpful to disable animations you are not using.

### Example Usage to Reduce Memory Footprint
|
||||
1. Remove `RGBLIGHT_ANIMATIONS` from `config.h`.
|
||||
1. Selectively add the animations you want to enable. The following would enable two animations and save about 4KiB:
|
||||
|
||||
```diff
|
||||
#undef RGBLED_NUM
|
||||
-#define RGBLIGHT_ANIMATIONS
|
||||
+#define RGBLIGHT_EFFECT_STATIC_GRADIENT
|
||||
+#define RGBLIGHT_EFFECT_RAINBOW_SWIRL
|
||||
#define RGBLED_NUM 12
|
||||
#define RGBLIGHT_HUE_STEP 8
|
||||
#define RGBLIGHT_SAT_STEP 8
|
||||
```
|
||||
|
||||
### Animation Speed
|
||||
|
||||
You can also modify the speeds that the different modes animate at:
