Rearrange the file layout in preparation of becoming a monorepo

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

-The `Colormap` extension provides an easier way to set up a different - static -
-color map per-layer. This means that we can set up a map of colors for each key,
-on a per-layer basis, and whenever a layer becomes active, the color map for
-that layer is applied. Colors are picked from a 16-color palette, provided by
-the [LED-Palette-Theme][plugin:l-p-t] plugin. The color map is stored in
-`EEPROM`, and can be easily changed via the [FocusSerial][plugin:focusserial]
-plugin, which also provides palette editing capabilities.

-## Using the extension
-
-To use the extension, include the header, tell it the number of layers you have,
-register the `Focus` hooks, and it will do the rest.
-
-```c++
-#include <Kaleidoscope.h>
-#include <Kaleidoscope-EEPROM-Settings.h>
-#include <Kaleidoscope-Colormap.h>
-#include <Kaleidoscope-FocusSerial.h>
-#include <Kaleidoscope-LED-Palette-Theme.h>
-
-KALEIDOSCOPE_INIT_PLUGINS(EEPROMSettings,
-                          LEDPaletteTheme,
-                          ColormapEffect,
-                          Focus);
-
-void setup(void) {
-  Kaleidoscope.setup();
-
-  ColormapEffect.max_layers(1);
-}
-```
-
-## Plugin methods
-
-The extension provides an `ColormapEffect` singleton object, with a single method:
-
-### `.max_layers(max)`
-
-> Tells the extension to reserve space in EEPROM for up to `max` layers. Can
-> only be called once, any subsequent call will be a no-op.
-
-## Focus commands
-
-### `colormap.map`
-
-> Without arguments, prints the color map: palette indexes for all layers.
->
-> With arguments, updates the color map with new indexes. One does not need to
-> give the full map, the plugin will process as many arguments as available, and
-> ignore anything past the last key on the last layer (as set by the
-> `.max_layers()` method).
