Release v0.13.0

Changelog

Version 0.13.0 (February 25th, 2022)

Summary

Mitiq is now compatible with the latest version (0.13.1) of Cirq! This update was blocked for a long time because of some technical difficulties. So, many thanks to @vtomole for finding a solution to this issue!
This should solve several dependency conflicts or warnings that you may have got when running pip install mitiq or pip install -U mitiq.

The HTML rendering of all PyQuil examples in our documentation is now fixed. Thanks @astrojuanlu for useful suggestions about readthedocs!

We also thank @Rahul-Mistri for adding GHZ circuits to our benchmarking module and for making Clifford circuits compatible with the Mitiq CDR technique (instead of raising an error as it happened before this release).

We discussed and approved the design documents (RFC) for two new error-mitigation techniques: learning-based PEC and digital dynamical decoupling. You can find them at this link. Special thanks go to @Misty-W and @Aaron-Robertson!
