Linting?

[Erotemic]

Hi, I'm interested in potentially hacking on this package, but I don't want to make a PR with a crazy amount of non-functional changes due to whitespace. My editor will automatically strip trailing whitespace and there is a lot of it in this repo.

Running something like:

pip install black
black -S pylatexenc

will fix a lot of the issues, but it also might be over aggressive. Not sure exactly what style of linting maintainers like here, but it would help my sanity of at least trailing whitespace was removed and if newlines between functions / classes / etc were somewhat normalized and consistent.
