SPC v2

[dabreegster]

This is the big new version, with these changes (please edit where I'm wrong):

• new per-household fields
• various changes to existing fields (adjusting enum number, removing the BMI enum, etc)
• adding time-use diaries
• expanding to Scotland and Wales
• adding multiple years of output

This PR has changes to the R scripts, Rust pipeline code, and web app.

Release-blocking tasks:

• [x] Wait for all the new county data, then rerun the pipeline everywhere
• [x] Create new config/ files for Scotland and Wales, choosing some areas we'll provide by default
• [x] Update all the docs
• [x] Figure out how lockdown output works without a single mean time-at-home

There are other ideas we might explore later, like squeezing down output file size by lazily calculating person-diary matches.

I reran everywhere. 294 successes, 96 failures. 124GB output uncompressed. Currently compressing stuff and then will upload to v2 directory.

Failed regions were all due to missing OA data, as expected. Scotland, most of the config/special regions.

South Yorkshire in 2022 failed due to a partial download; I'll rerun that one and upload.

43GB gzipped, slowly creeping its way to Azure!

I'm ready to merge this into main. We can release v2.1 and smaller follow-ups to add in missing areas, and incrementally improve the web app and any docs. Awaiting @HSalat approval.
