ergodox_ez: Update my keymap to v1.3

This updates my ErgoDox EZ layout to v1.3, which has the following
noteworthy changes:

* Added support for logging keys, by pressing `LEAD d`. Also included is
  a tool to generate a **heatmap** out of the logs.
* The arrow and navigation keys were rearranged again, and now require
  an additional key being held to activate. See the **base layer** for
  an image that shows where arrows are.
* The **experimental** layer has been redone, and is now
  called **ADORE**, and as such, can be enabled by `LEAD a` now.
* Switching between Dvorak and ADORE is now persisted into EEPROM, and
  survives a reboot.
