Improve parsing of local strings with punctuation

[andrewchouman]

This should fix #701. I decided to allow the punctuation: , . ; : ? ! " ' ` [ ] { } ( ) < >.

Hey @andrewchouman looks like the tests are failing due to black having some problems with parser.py and parser_tests.py.

Solid work, but I had a bit of feedback. Hopefully @systemcatch can chime in as well.

Just a few comments from me, overall this looks solid though.
