Support all the 0.2 Ferris variants (#12653)

* Support all the 0.2 Ferris variants

For the Compact, the High and the Mini, create a new directory so each
keyboard may have the correct USB descriptor and a readme with more
specific information about it.

For the Bling, also add support for the underglow functionality.

Change the "MANUFACTURER" string to "Cuddly Keyboards Ltd.", the
name of the company I incorporated to sell keyboards, and change the
default descriptor from "Ferris the keeb" to "Ferris 0.2" which is more
descriptive.
I didn't update the 0.1 variants as I don't intend to sell these kits
with "Cuddly Keyboards". The firmware is mostly there to support
existing users.

Update the "hardware availability" to point to my new website:
cuddlykeyboards.com.

* Add RGB mode toggle to my keymap and to the default keymap

* Improve wording in the readme
