Add compressed size to git-sizer output
This PR adds the compressed size of the .git directory to the output of the git-sizer tool, and makes a few cosmetic label changes to make the output more clear.
Notes
- The compressed size is calculated by computing the on-disk size of the
.gitdirectory. - The scale used to compute the histogram for the new
Compressed total sizeis 1e9, which is 1/10th of the scale used to compute it for theUncompressed total size(10e9). I'm open to feedback on whether or not that's the right estimate to use. - Label changes are meant to make the output more clear, after fielding questions for years about what "Total size" meant in the Blobs section.
- This is my first contribution to a Go codebase, and while I did more than just vibe-code it, I certainly relied on Copilot to make the changes. If there's a better way to have made these changes, I'm open to feedback.
Here's the new output run on a large repository, with indicators for where the output has changed:
