Regex got flagged as poorly written by automatic quality system. Also the pypi package "stringcase" raises a warning for a bad regex inside python.

It looks like moving all of the code from ROOT/bmt to ROOT/src/bmt triggered this quality gate feature. It caught a moderately bad regex from 5 years ago.

We also get this error for the pypi

stringcase.py:247: SyntaxWarning: invalid escape sequence '\W' --- return re.sub("\W+", "", string) ---
