Add MapShed and Subbasin Tests

[rajadain]

Overview

We repurpose the benchmark scripts to save their outputs, and then add an optional --verify parameter that will compare the live results against these saved outputs.

Also add a test script that runs the benchmark-mapshed and benchmark-subbasin scripts with the --verify parmeter to run the tests.

Also add a ruff script to format the Python scripts, and runs it to modernize them.

I did not add any tests to benchmark-sync because between MapShed and Subbasin we're covering all relevant use cases.

Closes #108

Testing Instructions

• Check out this branch
• Run ./scripts/setup to ensure you have the right Python setup
• Run ./scripts/server to ensure you have the service running
