* Add proper per-key RGB support

* Adjust LED positions

* Separate delta-gamma

* Fine-tune LED positions

* fix up GAMMA revision

* fix up tabs indentation to spaces indentation

* Fixed positioning and CS-SW defs for some LEDs

* Fix INS RGB position

* Fine-tune LED positions, fix default RGB

* Update readme's

* Rename LAYOUT_87H to lowercase 87h

* Formatting gamma's rules.mk

* Formatting delta's rules.mk

* Use smaller readme image

* Use smaller README image

* First support for 87H-T-SC and 88H-T-SC

* Update README

* Fix layout naming
