Keyboard: Panc60 (#3961)
* initial check in
* figure out the column pins
* temporary keymap
* guess the row pins
* fix matrix.c compilation errors
* use the LAYOUT_60_hhkb macro and tweak the keymap a little bit
* update readme
* Put my name everywhere
* Add QMK Configurator support
* figured out the row pins
* update readme to have reset info
* Fill in some blanks that are documentation related
* Update matrix.c
* add kb functions
* forego kbfirmware labeling
* add arrows and caps lock to function layer.
* add a LAYOUT_60 and LAYOUT_all macro
* missed a comma
* add configurator support for the two new LAYOUT macros
* Jack helped me with a new custom matrix
* add 60_ansi into rules.mk
