Universal downloader utilities

[nichollsh]

Several of the PROTEUS ecosystem models depend on data obtained from online sources: Zenodo and OSF, at the moment. This means they will each need code for downloading these data. At the moment, these are implemented separately for each repo.

However, we could consider creating a generic FormingWorlds/resource_getter repository for obtaining data (name TBD). This repo would then be imported by each of the FWL models, avoiding code duplication. It also means we can create tests for these utilities, rather than wrapping them under the 'physics' part of the models.

Yes, I think moving the data download functionality into its own repository would be useful for the reasons you outline; even having this pip-installable might be useful. I think the best way to go for now is to first merge PR #591, and then tackle this as a next step.

Agreed that we need a shorter-term fix in the meantime.
