Internet Archive backfill

[philpax]

At present, this PR contains the raw download of the entire wiki as the Internet Archive has it, up to 2021-01-01 (the OVH fire was 2021-03-10. Hmm. I should have used that date instead.)

This was obtained using

gem install wayback_machine_downloader_straw
wayback_machine_downloader https://wiki.jc-mp.com -t 20210101 -d archive

Next steps involve:

• removing anything that's not of relevance
• matching up every file to their corresponding article, including articles that don't exist i the 2014 dump
  • this also involves relocating the images, in whatever form that we have them
• extracting the actual content from each page, then feeding that content to a LLM to merge into the existing page/creating a new page

We can ideally pose this task well enough that it can be done overnight with local LLMs. It's going to take a bit of work to get it right, though.
