[21pt] Build ras2fim pipeline tool

[RobHanna-NOAA]

This py allows one or more units to be fully processed at all levels.. All defaults including pathing will be used where possible

Required Steps:

• Need a ras2fim pipeline wrapper tool (coming)
  • get_models passing in HUC, crs and source code
    - Optional - get s3 input X-National_datasets folder) (maybe check to see if it is already downloaded?)
    - Optional - Get correct DEM from s3 inputs\dems\ras_3dep_HUC8_10m (maybe check to see if it is already downloaded?)
    - ras2fim.py (check params)
    - ras_unit_to_s3.py (check params).
    • GVAL (optional)
      • run inundation on all benchmarks
      • push inundation results to S3.
      • process through GVAL
      • push to eval data to S3.

Requirements and Notes:

• Need safety checks at each major step.

Update: Mar 7, 2024: The sub step tools for inundating and running benchmark data per unit was more complicated than expect and was extracted to it's own issue 311 and PR. In that separate PR is a tool that can take in a HUC number and go to S3 to get all of the input files it needs to run ras2fim.
