Improving emoji coverage

[blakegearin]

Summary

Seems to be a known issue/common complaint ₁ that many newer emojis show as empty rectangles. Is this something Rebble could address?

Notes

• I realize it would likely need to be dependent on new glyphs being created; I have experience with pixel art and would be willing to help on this front
• Only related issue I could find was 77 ₂ which hasn't been merged despite being opened in June 2019

Have a look at pebble-dev/rebble-emojis#4 and pebble-dev/rebble-emojis#5. Discussion about anything in this topic should happen there I think. And feel free to contribute!
