add .git-blame-ignore-revs file to maintain provenance

[lstein]

To avoid git blame recording all the autoformatting changes under the name 'lstein', this PR adds a .git-blame-ignore-revs that will ignore any provenance changes that occurred during the recent refactor merge.

I'm sorry, I've gone to review this twice and never saved my comment.

I tried this PR but it didn't seem to change the git history my IDE reported, but also it didn't cause any issues. Maybe I don't know where to look.

It doesn't change the commit history, just the output of git blame. Files that were reformatted as a result of the indicated commit will show the last author to make a real change to the code.

I know this is an old PR, but I saw some discussion on Discord about possibly running black on the codebase, and so this would definitely be relevant. If you don't see it helping, you may want to run git config blame.ignoreRevsFile .git-blame-ignore-revs to tell git to use this file; I don't think it's the default, at least in older versions. You may also want to add --global to have this apply to all repos on your machine.
