Error in pipreqsnb: % and ! Characters

[RagingTiger]

The built-in magic commands seem to be throwing the string cleaning step in pipreqsnb:

Exception occurred while working on file /home/hckr/ianozsvald/kaggle_optiver_volatility/notebooks/20210825_light.ipynb, cell 1/36

SyntaxError: invalid syntax

The error seems to come from these lines in pipreqsnb's source. I suspect it has to do with the way the lines are being sanitized by this function. The offending Jupyter Notebook can be found here and the offending cell is the 1st one.

This should be an easy fix ... requiring only a few steps:

• 1: fork repo: https://github.com/ivanlen/pipreqsnb
• 2: update sanitizing function
• 3: send pull request

Unfortunately the maintenance seems to have died off ... so the main repo won't be reliable for using this tool moving forward.
