ergodox_ez: Upgrade my keymap to v1.4

* When toggling the key logging on or off, the LEDs will do a little dance.
* The keylogger is now optional, but enabled by default. Use `KEYLOGGER_ENABLE=no` on the `make` command line to disable it.
* The `TAB`/`ARRW` key was turned into a tap-dance key, allowing one to toggle the **ARROW** layer on by double-tapping, and as such, avoid the need to hold the key.
* The `-`/`_` key was turned into a tap-dance key too.
* There is now a way to travel time with the keyboard, toggle the feature on by hitting `LEAD t`.
