Rearrange the file layout in preparation of becoming a monorepo

Move the documentation to `doc/plugin/LEDEffect-Breathe.md`, sources under
`src/kaleidoscope/plugin/` (appropriately namespaced). This is in preparation of
merging plugins into a single monorepo.

-Provides a breathing effect for the keyboard. Breathe in, breathe out.
-
-## Using the extension
-
-To use the plugin, include the header, and tell the firmware to use it:
-
-```c++
-#include <Kaleidoscope-LEDControl.h>
-#include <Kaleidoscope-LEDEffect-Breathe.h>
-
-KALEIDOSCOPE_INIT_PLUGINS(LEDControl,
-                          LEDBreatheEffect);
-
-void setup() {
-  Kaleidoscope.setup();
-}
-```
-
-## Plugin properties
-
-The plugin provides the `LEDBreatheEffect` object, which has a single property:
-
-### `.hue`
-
-> The hue of the breathe effect.
->
-> Defaults to 170, a blue hue.
-
-### `.saturation`
-
-> The color saturation of the breathe effect.
->
-> Defaults to 255, the maximum.
