Show HN: Vanity Git commit hash generator

Hi HN!

This is just a fun little tool I made after I got nerdsniped by noticing that one of my commits naturally started with "fae". I thought that was cute, so I looked up existing tools that make vanity commit hashes, but none of them seemed great to me (and none supporting signing commits).

I learned a fair deal about how git actually stores commits while making this, and I think I came up with a novel way to generate a vanity hash: adding an extra header to the commit file.

This was just a quick project to satisfy my curiosity, but I thought you all might find it neat. Notice that all the commits in that repo start with "fae0"!
