It looks like something weird happened with the second to last commit 4bebc19, do you think you'd be able to try undoing and redoing the changes so that git doesn't rewrite the entire file? |

This pull request addresses #1770.
It correctly handles != inside of f strings, as well as f"{!a}" not returning an EmptyExpression error.
This also adds an error for conversion flags not being followed by brace characters, which would otherwise be a token error, unlike the Python implementation.
It also changes the print out for UnopenedRbrace / UnclosedLbrace to correctly print braces instead of brackets.
I've also included tests for expected brace characters and not equals operations inside of braces, as well as the expected EmptyExpression errors for f"{!a}".
