era1112 keymap for preonic (qmk#16064)

Added the keymap I have been using as a daily driver for the last month.

* good firmware 26 jan, best clicky mode stability so far

* modified to reflect master branch coding style

* further modified to reflect master branch coding style

* improving clicky stability, tuned down clicky delay duration

* changed name of keymap folder to use lowercase letters
