Chore(#88): Add menhaden workflow

[atyrell3]

Justification

New pipeline for adding menhaden data from publicly available FOSS and ACCSP data sources. Currently relies on manual download to data-raw, can be updated with API integration. Note that 2025 data is not yet complete, waiting on ACCSP data to update later this month.

Fixes #88

This is a proposed new workflow. We need it, so thanks for adding it.

However the function is not structured in anyway like every other function in this repo. It needs to be refactored to take filepaths as arguments. It needs also needs workflow script in data raw + other small documentation (see this contributing file). Easier to build pkgdown locally to view it

The static file should not be committed directly to the repo but put in the folder we all agreed static files would be added to. This is on the network drive.

EDIT: we have been using standardized names for the path arguments (yes, they are a mouthful and probably not great, but until we change them all we should be consitent). For example input_path_foss.

EDIT: Duplicated message. Apologies

Agreed on the static file and workflows. However, it looks like the function uses file path arguments, so it should work like the others
