T-route restarts

[quinnylee]

Closes #66
Adds functionality to generate t-route restarts from NWM standard analysis/assimilation outputs.

Additions

• Documentation and examples
• Functions to create t-route restarts
• More checks in prep_ngen_data in processor.py to see if we are preprocessing atmospheric forcings, channel routing runoff, or t-route restarts
• Unit tests

Testing

1. Tested new t-route restart example locally on macOS/arm64 and Ubuntu/x86
2. Ran pytests locally (except for the S3-related ones) on macOS/arm64 and Ubuntu/x86
   3. Attempted to run new t-route restart example and pytests locally on Ubuntu/x86. I get very strange errors when forcingprocessor tries to read the NWM output file:
   Edit: moved error documentation here pytests failing on ubuntu/x86 #68
   But since NRDS runs on arm nodes I'm inclined to not worry very much about this

Notes

• Haven't written formal pytests yet because I would need the required reference files uploaded to S3. Those files live here https://alabama.box.com/s/rcabrkvghyhuegk13cq8zdh03dzus043

Todos

• formal pytests
• h5netcdf issue (?) resolved by setting h5py==3.11.0

Another funky error when trying to run test_plotter.py on Ubuntu/x86
Edit: moved error messages here #68

Thanks for this feature @quinnylee! This looks ready to merge, though could you add a pytest that performs a prep_ngen_data() call for troute restart files? Ideally we have unit tests for each of the new functions, but I'm happy with just one test to make sure the feature works.

Here's a bunch of unit tests and a full prep_ngen_data test suite. It's a lot of tests but pretty fast.
