Configurable handling for index tracks and headings

[ybnd]

Description

Fixes #4234 by introducing more fine-grained control over how to handle index tracks and headings. Still very much a draft.

• [ ] Cleaner config (do we need all 4 options? type safety?)
• [ ] Refactor a bit, very sloppy now
• [ ] Check more thoroughly w/ real examples

To Do

• [ ] Documentation. (If you've add a new command-line flag, for example, find the appropriate page under docs/ to describe it.)
• [ ] Changelog. (Add an entry to docs/changelog.rst near the top of the document.)
• [ ] Tests. (Encouraged but not strictly required.)

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

Hi @ybnd,once you continue working on this PR and try to rebase master, you'll probably find a conflict with beetsplug/discogs.py but it's simple to fix. In the end you should have this situation:

• extract_release_id_regex method should be deleted from discogs.py
• extract_discogs_id_regex function should be imported from util.id_extractors

More details best look at the pull: #4633

Hope that helps and certainly get back to me with any questions! :-)
