Add a keymap for the Ergodox EZ meant to be used with a Bépo keyboard layout (French ergonomic layout) (#2141)

* Initial version of the Ergodox EZ Bépo keymap, TypeMatrix style.

* Update the readme file and add some handling of the keyboard LEDs.

* Toggling layer requires 2 taps.

* Remove a constant as it conflicts with an earier definition.

* Fix a typo in a type name.

* Fix the arrow layer that had a bad number.

* Second main version of my bepo keymap, after the tests of the first one.

* Fix the triggering of the function layer and the handling of the LED.

* Reduce the shining of the LEDs.

* Fix the swap layer (that required a keypress on the other side of the keyboard to be deactivated).

* Duplicate some of the mouse button for easy access.

* Move some of the secondary functions out of the center keys.

* Slightly slow down the mouse and mouse wheel.

* Update the comment and readme.md for the V2 of the keymap.

* Invert button 2 and 3 of the mouse. Really fix the SWAP layer.

* Test with the right alt modifier added as secondary function (on hold) of the space keys. The right alt key becomes a left alt one.

* Add specific shift/ctrl for the FN layer; move some mouse keys around to help with that.

* Remove one FN modifier-on-hold key that was not useful.

* Duplicate the FN layer inside the MOUSE layer.

* Add support (not tested yet) for macro recording and play on a single key as a tap dance.

* Allow to stop recording the macro by tapping once on the macro key (still un-tested).

* Add support for macro recording using some tap dance.

* shorten a comment.

* Reinstate the FN toggle on the percent key (so that there is an FN toggle on the right-hand-side).

* Fix some comments and update the link to the most up-to-date image.

* Small fix to the keymap images.
