feat(layout): add galite (@almk-dev) (#6273)

### Description
Adding `galite`, a hybrid tweak of GalliumV2, Graphite, and Colemak-DH,
with more standard punctuation keys.
The [final
version](https://www.reddit.com/r/KeyboardLayouts/comments/1iqo9ob/galite_galliumgraphite_hybrid_with_simplified/)
is based on discussion and feedback from a
[thread](https://www.reddit.com/r/KeyboardLayouts/comments/1ipdk2t/what_are_the_communitys_thoughts_on_a_gallium_row/)
on the AKL community subreddit.

Repo with details, notes, and stats:
