v1.2 Release

Baseline firmware build for nibble keyboards. Includes ANSI/ISO keyboard layout and encoder, LED, and macro keys. If you want VIA support, flash nibble_via.hex using QMK Toolbox. nibble_default.hex does not include VIA support. Also includes support for future remote keyboard & macropad functionality.

If you want to build instead of flashing the precompiled binary, you'll need to clone or fork the QMK firmware repo and copy this into the keyboards directory, and build with make nibble_kb.

Added ISO keymap and forward compatibility for ISO/ANSI PCB (Rev2).
Added "debug" keymap and binary file for debugging stuck modifiers.
