* Add the e7-v1 keyboard
The e7-v1 is a 75% keyboard made by Exclusive based on an Atmega32u4
pub with RGB lights on top and backlighting.
This PR add supports for the regular ANSI layout and ANSI split
backspace layout. No ISO yet :(
* My e7-v1 keymap
Difference from base layout:
* split backspace
* Home & End on last keys of row 0 instead of Insert/Del
* Fn is on the End key when hold
* supports both a windows/linux keymap and osx keymap
* layer change is reflected in the rgb leds of the logo
