Merge remote-tracking branch 'upstream/master'
* upstream/master: (1239 commits) Update ez.c removes planck/rev3 temporarily Move hand_swap_config to ez.c, removes error for infinity Update Makefile ergodox: Update algernon's keymap to v1.9 Added VS Code dir to .gitignore Support the Pegasus Hoof controller. [Jack & Erez] Simplifies and documents TO add readme use wait_ms instead of _delay_ms add messenger init keymap Add example keymap Adding whiskey_tango_foxtrot_capslock ergodox keymap Unicode map framework. Allow unicode up to 0xFFFFF using separate mapping table CIE 1931 dim curve Apply the dim curve to the RGB output Update the Cluecard readme files Tune snake and knight intervals for Cluecard Tunable RGB light intervals ...
