PDF and XML files imported as figure files

[joemull]

PDF and XML files are not recognized on import as editable files and so are imported as figure_data_files:

imports/utils.py

Line 302 in e54b59a

handle_file_import(row, article, zip_folder_path)

imports/utils.py

Lines 357 to 360 in e54b59a

	if file.mime_type in files.EDITABLE_FORMAT:
	article.manuscript_files.add(file)
	else:
	article.data_figure_files.add(file)

Seemingly as a result, they do not appear in the typesetting plugin in the place that they can be converted to galley files easily:
https://github.com/BirkbeckCTP/typesetting/blob/48720ad13775a640d5349e2f652288526f693422/templates/typesetting/elements/production_files.html#L20

As a quick fix, we can class these as manuscript files on import.

This has now been effectively deprecated:

imports/utils.py

Lines 535 to 537 in a7451e3

	# Turning off file imports to prep for overhaul
	# if folder_path:
	# handle_file_import(row, article, folder_path)

The importer now only allows PDFs:

imports/utils.py

Lines 400 to 407 in a7451e3

	if (primary_row and primary_row.get("PDF URI")):
	try:
	import_galley_from_uri( article, primary_row["PDF URI"])
	except Exception as e:
	errors.append({
	'article': primary_row.get('Article title'),
	'error': f'Failed to import PDF: {e}',
	})

The use case for importing a manuscript file would be: a journal has articles in progress during migration.

But this would likely not happen with more than 10 or so articles, so the benefit of writing an importer would not be felt, since that many can be done manually in not too much time.

So, what if we rethink this feature as a more generic file importer, where you can control what types of files are being imported--not just MS files but all kinds of files in Janeway.
