Options:

• Put history data in other branch, and get with GitHub API Get history data directly from raw.githubusercontent.com ? #52
• Use other hosting service than GitHub Pages, with larger limit

Hitting the issue again.

Partly because of #66

we could trigger GC periodically, to remove obsolete revisions from PR directory

CC @MylesBorins is this something you could help with? This project has become critical infrastructure for TC39. Perhaps it could get some additional gh-pages space?

Compressed the JSON data (sections.json, parent_diff.json) by 5366e7d, this reduces the history data from 8.2GB to 4.7GB (13MB per each revision to 7.5MB per each revision), and we can have nearly twice revisions in 10GB limit.

Also compressed the snapshot HTML (index.html) by 73e6c8a , this reduces the history data to 1.3G (2.7M per each revision),
and we can have thrice revisions in 10GB limit (~3700 revisions in total).
