I'm using this project on Docusaurus, a static site generator, to monitor the build output size

Example PR comment:facebook/docusaurus#10470 (comment)

Monitoring by file size is great, but in our case, we emit too many output files to monitor them all without creating noise, so I only added a "representative" list of output files.

What would be a great addition for us would be to have the ability to compare the before/after size of a whole folder. Eventually be able to break it down by file type, so that we could detect if JS, CSS, or HTML total output size increases after a PR.

I'm wondering if this could be part of this project, or if it's out of scope and should be a separate tool.
