Add COSPAD to QMK and add functions to read HSV (#2156)

* Added functions to read HSV values

I have added three functions to rgb_light.c to be able to read the hue, saturation and value from other places.
They are rgblight_get_hue(), rgblight_get_sat(), adn rgblight_get_val().

* Create keymap.c

* Add COSPAD support to QMK

I have ported the COSPAD numpad to qmk.

* Update readme.md

* Update cospad.c
