Parse custom roles from Calibre opf

[random-human-being]

As of recent releases, bookshelf can scan Author and other select roles from an ebook/audiobook metadata.

Calibre allows the user to define custom columns for a variety of metadata.
Among these, the user can specify that a column contains a person's name (or list thereof).
This is the most straightforward way to include a field for translator, editor, foreword author, etc

For example, if I wanted to add a "Translator" field to my Calibre library metadata I would go to:
Preferences > Add your own columns > Add custom column
and there select the following:

• Column type: "Comma separated text, like tags, shown in the tag browser"
• Contain names: yes
• Column heading: Translator
• Lookup name: whatever

... and leave the rest blank

Then the newly added Translator field can be edited from the GUI.
If I then change the default blank value to a name (or a comma-separated list), Calibre will add a line to the corresponding metadata.opf, which ends up looking like the following two examples:

https://pastebin.com/sMDyra4D

The line that is added is a bit verbose, but the relevant metadata can be extracted as follows:

(apologies for posting a script in Python rather than C#, but I am not familiar with the latter)

Could parsing of these fields be added to Jellyfin Bookshelf, and shown in the "People" section at the bottom of the ebook page?
