`$` in entry causes fatal error

[disastrid]

I've been using the CLI to parse a bibtex file of conference proceedings, which includes abstracts. Every time the parser hits a dollar sign ($) it errors out (it took me awhile to figure out which character was causing the problem).

If anyone else has this issue you can escape the characters in the text with \$ as a temporary fix.

Here's the error output:

Thank you for taking the time to make a bug report! What version of Citation.js are you using?

I am only able to reproduce this in the case of unbalanced $ which do need to be escaped in all TeX-based syntax, as far as I am aware. If you have a different problem, please provide more information.
