spaces added in f-strings

[jbloom]

snakefmt 0.10.0 re-formats f-strings that are originally like this:

print(f"{x=}")

to be like this:

print(f"{x =}")

I don't think this is intended, is it?

This is essentially a duplicate of #220. I'll close this in favour of that issue and you can follow along there
