Zeal60/Zeal65/M60-A implementation (#3879)

* Initial version of zeal60

* WIP

* Fixes issue #900

* Adding RGB underglow functionality.
Fixed a compile-time conflict caused by enabling RGB underglow functionality.

* Refactor RPC protocol

* Fix last merge

* README for RGB underglow updated.

* Additional README changes.

* Adding RGBW strip software-based current-limiting functionality.

* RGBW current-limiting functionality should be handled by RGBSTRIP_MAX_CURRENT_PER_LIGHT instead.

* Updated README to reflect implementation of built-in current limiting.

* Keymap readability improvements.

* Minor keymap improvements.

* Fixed LED driver init sequence, formatting

* Dimming implementation tested, working.

* Stab LEDs synced with spacebar hits in effects.

* RGB underglow tested and functional. Simplified README for RGB underglow.

* Undid accidental file deletion from previous merge conflict. Safer values for RGB underglow.

* Improved arrow key positions in keymap.

* Added functionality to correct uneven RGB underglow. Refactored related code.

* Reverted to safer values for underglow.

* Changes for v0.3

* Custom LED brightness scaling will take place after current adjustment in order to avoid being overridden.

* Create keymap.c

Added split backspace and split shift to ISO layout

* Create config.h

Turned on LEDs for new layout

* Fixed bug where left spacebar stabilizer LED (LC06) would adopt color of row above.

* Added hhkb_wilba keymap

* Update keymap.c

* Update keymap.c

* Update keymap.c

* Added indicators, full param setting via host

* Added "mousekey" layout

* Added Zeal65 support, factory test mode

* Keycode safe range changed, caused bugs

* Bumped EEPROM version due to change in QMK keycodes

* Disable HHKB "blocked" LEDs if KC_NO in keymap

* Added "disable_hhkb_blocker_leds"

* Required overridden function for keymaps in EEPROM

* Added polar coordinate mapping, effect speed

* Force Raw HID interface number to 1 always

* Fixed last merge from master

* Added effect speed to default keymaps

* add BACKLIGHT_ prefix to vars

* add BACKLIGHT_ prefix to vars

* Keymap speed effect; keymap improvements/fixes
Readme updated to match changes

* Refactored to use common IS31FL3731/I2C drivers

* Fixed make rules, backlight disabled feature

* Make split rightshift default for Zeal65

* Added M60-A as a "version" of Zeal60.

* Renamed IS31FL3731 driver functions

* Fix suspend_wakeup_init_kb() being defined twice

* First pass refactor dynamic keymaps

* Updated to changed I2C and ISSI drivers

* Refactor zeal_color.* usage to quantum/color.*

* Updated Zeal65, fixed dynamic_keymap

* Major refactoring of Zeal60 backlight and API

* Lots of little cleanups

* Added readme.md

* Added readme.md

* Added LAYOUT_60*() macros, refactored and cleaned up default keymaps

* Fix compile error in suspend.c

* Added Zeal65 LAYOUT macros, info.json

* Added rama/m60_a, deleted zeal60/keymaps/m60_a

* Fixed rama/m60_a/keymaps/proto

* Fixed compilation error for suspend.c

* Requested changes for PR

* Fixed readme.md images

* Another readme.md fix

* Added drashna's requested changes
