Migration to only have a main branch

[mikaelacaron]

I wanted to change it up and ONLY have a main branch to make it easier to contribute to this project.

Going further:

• main will be the default branch that all PRs will merge into
• I'll use tags to tag when versions are released to the App Store.
• dev is going to be deleted

Warning

Pretty sure that this breaks everyone's fork of the repo. You may need to change settings to get the new branch, or just delete your fork and create a new one, and then clone onto your local computer again

Drop comments here if you have any issues! Thanks to everyone who contributed to this project! THIS YEAR! It'll be shipping!
