Improve API tools for file-searching

test_entry = 10311

test_catalog = EmpiarCatalog(test_entry)

entry_data = test_catalog.fetch_entry_data(test_entry)

entry_data["imagesets"]

gives me an overview of the available datasets. entry_data["imagesets"][i]["directory"] gives me the location of these datasets. But I don’t know how to check the contents of this directory (except by checking the EMPIAR entry manually!).

There is entry_data["imagesets"][i]["data_format"]) which tells me if it is MRC or TIFF. Although it wouldn’t tell me if the files are .tif or .tiff

This is related to the absence (or non-accessibility) of mapping metadata file when API written. Check if that is now public. If not might be able to adapt CLI functionality for use by API.
