[Feature Request] Change Photo Bubble to Contact Initials

This feature request came from u/Sure-Temperature in this reddit post Below is how it currently looks, along with a mockup I made. I used this font.

I can see how this would be a nice addition. I don't think the license allows this kind of use of Apple's SF font, though. I'd also like to avoid bundling any extra fonts with the app if possible.

For reference, here is how some other apps handle it:

Google Messages

Pulse SMS
