Keyboard: xealous (#3731)

* Keyboard: HandWired/XeaL60

* Updated rules.mk

* Mapping for layout was flipped

* Figured out how to re-map bad pins.

* Updated Keymap

* Enabled audio, Forced NKRO

* Added QMK_KEYS_PER_SCAN

* Removed more unnecessary files, since split_keyboards are in main QMK branch already.

* Simplified rules.mk in rev1

* Removed i2c from matrix.c

* Re-formatted to 4 spaces per tab,

* Changed note for NUMPAD

* Added I2C support back!

* Fixed keyboard mappings. Both sides work

* Moved i2c configuration from keymaps/default/config.h to config.h

* Changed SCL_CLOCK to 400000L

* Added DEBUG_MATRIX_SCAN_RATE for future optimization efforts

* Removed row2col code to clean up matrix.c

* Scan rate from 2100 -> 4200 by using Nop instead of waiting 30us between columns.

* Further optimized column reading via optimized_col_reader.

* Immediate key-recognition

* Switched back to own implementation of SPLIT_KEYBOARD. Will optimize so that slave interrupts master.

* Moved scanrate debug messages to another file.

* Made matrix_scanrate.c compile if CONSOLE_ENABLE is off. Updated to latest i2c.c

* Latest i2c uses a few bytes for lighting information

* Optimizations in i2c.h to determine buffer size.

* Disabled a whole bunch of features. TODO: Test that keyboard still works fine.

* Minimum #define NO_ACTION's with still working keyboard

* Fixed matrix not working due to offsets not being respected

* Added numlock button for keymap.

* Use I2C_KEYMAP_START offset

* Removed serial, Backlight and RGB support

* Removed need for split_flags.

* Added audio on and off for numlock.

* Renamed from xeal60 to xealous, simplified build system.

* Used more shared split_common code.

* Updated audio code.

* moved tone_qwerty and tone_numpad to config.h. Removed keymaps/default/config.h

* Added more shortcut keys in _FN layer. Increased debounce to 6ms due to fencepost error.

* DF used with incorrect argument. Custom_keycodes no longer required.

* Fixed bug in update_debounce_counters which was resulting in no debouncing!

* Removed unnecessary #include
