AWS 2-5: Update TDX Hydro Dataset

[rajadain]

Folks at LimnoTech have a version with custom attributes that connects the streams to the basins and allows for quick watershed delineation. We need to replace the current version with that, so that each stream has the necessary attributes for that work.

@ptomasula will upload the dataset to s3://data.mmw.azavea.com/.

Once the dataset is available:

• [ ] Ingest it locally into postgres using ogr2ogr
• [ ] Export it into sql using pg_dump
• [ ] Import it on staging
