ZMK Config for 3x5_2

• Mainly for my Corne-ish Zen, hopefully going to be for a Cygnus soon…
• I have successfully moved to mostly using a 3x5_2 layout like a Ferris Sweep.
• This layout is more or less mirrored on my QMK firmware userspace from a layout developed on my QMK firmware fork.

Quick Note on Thumb Position Strategy:

• I prefer to rest my thumbs neutrally just outside (roughly 1u) outside my homerow pointer fingers. (Primary thumb, anchor position)
• The secondary thumb key is outside that anchor position, where I curl my thumb towards my palm to reach it.
• Compressed layouts like the Bancounver40 are more usable, and the overall footprint of the keyboard is smaller.
• We'll see about the long-term ergos of this, it's new to me.
