Don't include 'subscript' links

[HebeHH]

The codebase works by assuming all links in a Wikipedia infobox table row are relevant to that keyword. This is not always the case.

Specific issue: Random notations in the row will include links.
For example, the Successor section for Laodice IV's position as consort gives Unknown, then notes (in notation format) that this is because the Antiochus V didn't marry.

In the graph, this turns into Antiochus V being her successor.

Useful note:
This specific kind of note is using the HTML format <small>:

Suggested fix:

1. Ignore links inside <small> tags
2. Ignore links inside brackets
