ModuleNotFoundError after fresh install

[vinayak-mehta]

chardet (a dependency for pdfminer.six) isn't installed in Python>3 when installing Camelot using pip install camelot-py[cv], which seems a bit strange since the build was successful on master 5 days ago. Will trigger a new build to check. The issue was first seen here.

Thinking of creating a release with chardet in the requirements, as a short-term fix.

This is the traceback with $ camelot --help or >>> import camelot.

$ camelot --help
