Create tool to easily submit bill nicknames

Using the GitHub API, we can pretty easily automate pull requests that add well-formatted lines to this CSV.

This would make it easier for people to contribute to the repo and help reduce the headaches of editing pull requests to conform to the csv schema. Probably a job for code in a different repo, but I'm going to open this issue in case people have thoughts.

Somebody else should probably still review anyways in case somebody tries to submit malicious strings that others don't escape or otherwise jibberish. An integration test which checks for proper format would still be helpful.

Yeah, for sure.

The idea would be to have something generate a PR with the proposed changes, then repo owners would review.
