* Converter: add XT USB converter from TMK * Converter: port TMK code for USB converter to QMK * Apply requested changes after code review by @drashna - use "pragma once" instead of include guards - use LAYOUT instead of KEYMAP - allow customisation with matrix_init_user() and matrix_scan_user() - set BOOTLOADER instead of BOOTLOADER_SIZE - Add XT_ENABLE to OPT_DEFS * Remove unnecessary lines
