ergodox: Update algernon's keymap to v1.6

Major changes include:

Base layer changes
------------------

* The parentheses & bracket keys have been merged: tapping them results
  in `[` or `{` (if it was shifted), double tapping leads to `(`.
* The `:;` and `-_` keys are now available on the base layer, on
  their **ADORE** location, too, just below `[{(`/`]})`.
* The `Apps` key has been replaced by `F12`.
* The `-`/`_` is no longer a tap-dance key.

ADORE layer changes
-------------------

* Adjustments were made to the **ADORE** layer, to separate some
  inconvenient combinations.

Miscellaneous changes
---------------------

* `LEAD u` now starts the symbolic unicode input system, instead of the
  OS-one.
* The mouse acceleration keys on the **Navigation and Media* layer have
  been turned into toggles: tap them once to turn them on, until tapped
  again. Tapping an accelerator button will turn all the others off.
* When the **ARROW** layer is on, the *red* and *blue* LEDs light up
  now.

Heatmap
-------

* The built-in keylogger has been greatly enhanced, it now outputs the
  pressed state, and the layer (Dvorak or ADORE). As such, the
  `ADORE_AUTOLOG` option has been removed, instead there is
  `AUTOLOG_ENABLE` now, which when enabled, makes the keylogger start
  when the keyboard boots. It defaults to off.
* The heatmap generator received a lot of updates.
