📚 Description

Striping comments with regex is tricky. (see #56, #155 and added test in this PR -- thanks @danielroe for idea in #155 (comment)!)

This PR makes stripping comments for syntax detection utils so users can opt-in.

In the future (maybe major versions) we might migrate to a native parser.
