• ci(deploy): add a deduplication stage

  Add a deduplication stage that uses the new dedupe.py script to cut down on
  duplicated deployment assets.

• feat(dedupe): add a deduplication script

  Add a script capable of deduplicating assets used between multiple build
  targets.

  When attempting to play with sphinx's asset paths I noticed there was a lot of
  logic around preserving relative links. It didn't seem like they want to allow
  usage of an asset path outside of the build directory.

  The WebSupport class seemed to allow some of that flexibility we were looking
  for, but unfortunately it still assumes the conf.py is in the source directory
  and has issues working with other Sphinx extensions like ifconfig.

  Given what we are doing seems to be a niche usecase, we can address this with
  a little post processing using lxml filters.

• feat(docker): add lxml as a requirement

  Add lxml as a requirement for a deduplication script we'll use to reduce
  deployment size on GitHub.

This script can cut our current deployment size down from 1.2 GB to 288 MB in ~30 seconds.

Some of this logic may be a bit wacky, I was not giving this my full attention. I need to do a proper review tomorrow.

Eh, I think this is still fine for what we're doing here. Ready for other reviews.
