[Keymap] Adding Fancy and Bongocat Keymap to Mercutio Keyboard (#11520)

* Initial commit on new clean branch. Testing out functionality of oled and encoder for default features.

* Cleaned up the initial push and removed the fancy keymap until the extra features and functionality can be tested and made more user friendly.

* Cleaned up the readme some more, compiled and tested both default and via keymaps, and did another round of checks to prepare for starting the PR.

* Cleaning up the keymap to meet expected formatting in a couple places and also adding in the TAP_CODE_DELAY after newly encoutnered encoder issues and inconsistencies.

* Initial commit of branch specifically for implementing the more complicated fancy keymap as I expect the main PR to be approved first.

* testing bongo cat out

* Progress with intended OLED behavior. Needs to be cleaned up still.

* Cleaned up bongocat and added WPM display on it.

* Almost there. Need to rethink the layer checking in encoder.

* Fixing all the merge issues I didn't check before doing the last commit. Learn from my mistakes, check your commits.

* Fixed and updated fancy firmware and bongocat firmware.

* Updating license year since I will be doing a PR anyway.

* Update keyboards/mechwild/mercutio/keymaps/fancy/keymap.c
