Allow inline comments

[jakewilliami]

Hi team, thanks for all the work on this library! It's very useful for a simple use-case I have.

I have encountered an issue with some of my bibliographies not parsing, for example:

@article{fischer2019primer,
  title={A primer to (cross-cultural) multi-group invariance testing possibilities in {R}},
  author={Fischer, Ronald and Karl, Johannes A},
  journal={Frontiers in Psychology},
  pages={1507}, % A comment here
  year={2019},
  publisher={Frontiers},
  doi={10.3389/fpsyg.2019.01507}
}

This is because there is a comment after one of the fields. This is allowed by the BibLaTeX (as far as I know), but not by Typst's biblatex. Are there any plans to support these comments in future?

N.B.—: I've always been a little confused about comments in bibliographies, as Emacs tried to add comments as @Comment but BibLaTeX never seems to like this. Perhaps that's a deprecated comment style. I've never bothered to read into it...
