Pytest Warnings (#212)

* test_channel_metrics

* fix #205 (comment)

* scipy/sparse find_common_type deprecation

* ignore warnings related to cvxpy

* try ignore all cvxpy warnings

* try: ignore a line in a third party package

* try whole path

* try: omit virtualenvs

* add coveragerc to pytest path

* upgradepytest cov version

* remove coverage

* numpy: Ensure you extract a single element

* upgrade coverage

* Revert "scipy/sparse find_common_type deprecation"

This reverts commit fb9d3a0.

* update toml

* comment out matsumoto fidelity failure

* test: don't ignore cvxpy

* pylint + cleanup

* no else return

* upgrade scipy
