Feature Request: Support for the SWR Package in FloPy

[eacuellarq]

Currently, FloPy provides extensive support for many MODFLOW packages, but it seems the Surface-Water Routing (SWR) package from MODFLOW-NWT is not included. The SWR package is crucial for modeling surface-water and groundwater interactions, and having it integrated into FloPy would be highly beneficial for many users.

I would like to request the following:

Official Support for SWR: If feasible, adding SWR to FloPy would significantly enhance its capabilities.
Guidance for Custom Implementation: If official support is not planned, could you provide documentation or guidelines for extending FloPy to include unsupported packages like SWR?
Potential Benefits:

Expands FloPy’s functionality for coupled surface-water/groundwater modeling.
Allows for streamlined workflows when using MODFLOW-NWT with SWR.
Willing to Contribute:
I am happy to assist by testing or providing feedback if SWR support is developed.

Additional Context:
If there are known workarounds or plans for this in the future, any information would be greatly appreciated.

There is a ModflowSwr1 class in the flopy.modflow.mfswr1 module, I see that while we have a notebook about post-processing SWR results it doesn't show the package itself
