era1112 keymap for preonic (#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

+ * How to figure out tap dance state: interrupted and pressed.
+ *
+ * Interrupted: If the state of a dance dance is "interrupted", that means that another key has been hit
+ *  under the tapping term. This is typically indicitive that you are trying to "tap" the key.
+ *
+ * Pressed: Whether or not the key is still being pressed. If this value is true, that means the tapping term
+ *  has ended, but the key is still being pressed down. This generally means the key is being "held".
+ *
+ * One thing that is currenlty not possible with qmk software in regards to tap dance is to mimic the "permissive hold"
+ *  feature. In general, advanced tap dances do not work well if they are used with commonly typed letters.
+ *  For example "A". Tap dances are best used on non-letter keys that are not hit while typing letters.
+ *
+ * Good places to put an advanced tap dance:
+ *  z,q,x,j,k,v,b, any function key, home/end, comma, semi-colon
+ *
+ * Criteria for "good placement" of a tap dance key:
+ *  Not a key that is hit frequently in a sentence
+ *  Not a key that is used frequently to double tap, for example 'tab' is often double tapped in a terminal, or
+ *    in a web form. So 'tab' would be a poor choice for a tap dance.
+ *  Letters used in common words as a double. For example 'p' in 'pepper'. If a tap dance function existed on the
+ *    letter 'p', the word 'pepper' would be quite frustating to type.
+ *
+ * For the third point, there does exist the 'TD_DOUBLE_SINGLE_TAP', however this is not fully tested

+A preonic keymap that includes:
+- doubletap tapdance for caps lock
+- rotary encoder
+- macro record/playback
+- light on/off
+- sound on/off
+- blink-on-keypress w/ on/off keystroke
+- beep-on-keypress w/ on/off keystroke (this has stability issues when typing fast, still trying to remediate)
