[FEAT] Get 1D in altitude working so we can debug vertical solver easier

[aaronjridley]

The code should be able to run in 1D, especially in the vertical direction, so that we can debug vertical processes easier.

Steps:

• [ ] Get grid inputs to recognize only one lat/lon is being requested
• [ ] Set up grid appropriately
• [ ] Put checks so that all horizontal gradients are ignored if 1D
• [ ] Add 1D output file type
• [ ] Make python code to allow visualization of 1D files
