please rename master branch to main

Hi,

I was looking at the differences between the inkstich fork and the original
https://github.com/inkstitch/pyembroidery/blob/6e6b53e93b94a8b70a15d0ff8b4f976ef844c8a5/README.inkstitch.md

As there aren't that many open source libs, I was wondering if it's possible to unite the efforts in a single repo, or at least minimize the differences?

Our primary branch is named main.

Since this is the new github standard, would you consider renaming master branch to main?

We have a differeng G-code writer that satisfies the needs of Ink/Stitch users.

I have no idea what this is. Could it be in a single repo?

We have a couple of changes and bug-fixes.

This should be the fork's responsibility to open PRs to merge their changes in this repo.
