Re-sort analog and digital items

[dbietila]

Try presenting high-metadata analog item types above the digital audio items on Series pages (and potentially other contexts).

This issue has been satisfied by showing only original items (items without a isFormatOf relationship). However, this raised another issue because in the series view it is not obvious if there are playable media.

This has been resolved with https://github.com/uchicago-library/mlc_ucla/pull/36.

• Series only display first generation items, as these should have the most relevant metadata.
• Items display the whole descendant tree grouped by generations and sorted first by medium.
• Series include a list of all formats within, with an headphone icon label on the "Sound" format when at least one sound item has a Panopto link.
• Item view also lists all formats in its descendant tree, in the metadata table.
• Item short records include an icon stating 'has conversions' when it has children (has has_format field)
• Tried to surface for each item on its short record an icon indicating if there is a Panopto link within its descendant tree, but this made a series' view python request to be take over 54s instead of less than a second.
• Items with a Panopto link are also made more obvious with a large headphone icon in the short record.
