[1pt] Remove deprecated references to LID selection functionality in CatFIM

[EmilyDeardorff]

Previously, there was a functionality in CatFIM that allowed you to just run one LID. This has been long deprecated but parts of it have still been left in the code. I am removing the references to lid_to_run from CatFIM in order to keep the CatFIM scripts cleaner.

This issue is referenced in the CatFIM Epic Card.

Changes

• tools/catfim/generate_categorical_fim.py: Remove references to lid_to_run variable.
• tools/catfim/generate_categorical_fim_flows.py: Remove references to lid_to_run variable.

Testing

Tested on a stage-based and flow-based CatFIM run of HUC 05110003.

It would be good to test stage-based and flow-based on a few other HUCs to confirm that the changes haven't triggered any bugs.

Deployment Plan (For developer use)

How does the changes affect the product?

• Code only?
• If applicable, has a deployment plan be created with the deployment person/team?
• Require new or adjusted data inputs? Does it have start, end and duration code (in UTC)?
• If new or updated data sets, has the FIM code been updated and tested with the new/adjusted data (subset is fine, but must be a subset of the new data)?
• Require new pre-clip set?
• Has new or updated python packages?
