Gallery viewer testing fixes

[will-moore]

Update download_urls page and gallery_viewer pages to fix various links and reduce code logic.
Fixes #63

Instead of complex code, we add all the special case handling to IDR/idr.openmicroscopy.org#220.

This PR needs the table from that PR. We can temporarily specify it by adding it to the query string:

To test:

• Go to idr-testing/download_urls/?tsv=https://raw.githubusercontent.com/will-moore/idr.openmicroscopy.org/refs/heads/update_download_urls/_data/download_urls.tsv
• The client_path column has a link that is derived from the client_path itself, and the replace this and with this columns. The client path text is shown with the derived URL being the link. These links should all be valid (green).
• Check links to images (ID column) for various rows (studies), particularly those marked as failing in https://docs.google.com/spreadsheets/d/1Q8ZSMa3ItTDUqJGYwYP3j5yDsVqfAsopD5ozD7JL74Q/edit?gid=469737557#gid=469737557 - E.g. idr0003, idr0037
  • Test various GitHub studies - Does the text/links make sense? The "download" ftp link should be valid (from tsv file) and the companion file link should work, but the tiffs may not for all cases.
  • idr0138 shows download links for every zarr chunk! Not ideal but no better solution?!?
  • The link should go to an Image page (or iviewer for zarr images)
  • Image page download links should be green (valid)
  • Test various rows that have different replace this columns, e.g. idr0145, idr0021 etc.

@dom updated this on idr-testing just now.

Thanks Will. Looks good to me! But maybe @francesw could so some random testing too? Easy to miss something.

Tested random selection of non-zarr studies. Download Image Files pages working for them as expected.

As discussed with @dominikl this morning, we will ONLY show images with externalInfo set in iviewer - so we can use that for the is_zarr test.
We can remove the idr0138 exception, since Dom will remove externalInfo from idr0138 (since the data is on file-system that will no-longer be accessible).
