Switch to TigerRD18 source

[johnseekins]

Data in https://www2.census.gov/geo/tiger/TIGER_RD18/ appears to be more correctly up to date than data we collected from the Redistricting Data Hub. This code switches us to using that data instead. And also includes steps to upload bulk boundary files to S3.

Two major concerns:

1. Is this datasource relatively accurate (and how can we verify it)
2. Are the manual districts (MD, NH, VT, etc.) correct?

I've got a few addresses that have been flagged as incorrect to test, I wouldn't know how without it being added to Mapbox. I think the manual ones look right

I just did a fresh checkout of this and poetry install, then did a poetry run scripts/get-shapefiles.py and got an error --

ModuleNotFoundError: No module named 'utils'

Possibly a missing file or dependency there?

Missed adding a file. Dang git.

Thanks -- that worked. I"ll download these and run them through our (unrelated to OS) geo stack and see if I can verify that the districts look good. Probably wont' be until monday, so feel free to merge w/out my review.

@John Seekins -- I might be looking in the wrong spot here, so double check me, but:

• I did a fresh checkout of out https://github.com/johnseekins/openstates-geo/tree/tigerrd18-source
• i did a poetry install, then ran poetry run ./scripts/get-shapefiles.py and poetry run scripts/to-geojson.py
• i looked at my output KS SLDU geojson, and it appears to be showing me the 2025 shapes. This is most visible if you pop the file into https://geojson.io/ and look in the bottom left corner; district 39 has an "r" shape instead of a :moyai: shape. https://ballotpedia.org/Redistricting_in_Kansas#District_maps

Ah better yet here the generated geojson --

That's what I'm seeing with tests, too. I think we may need to add overrides for some jurisdictions.

Cool. I dropped my test case in the other bug, but FYI:

712 Main St, Scott City, KS 67871

[lat] => 38.480357
[lng] => -100.906731

Changes from 33 (now) to 39 (future), it's in the "r" shape of the district in the bottom left corner.
