pyGSTio/pyGSTi: Version 0.9.5

This significant update adds the following functionality:

• Direct Randomized Benchmarking (DRB) method. Includes sequence selection and data analysis routines (see new tutorials 17-18).
• Improved Clifford Randomized Benchmarking support (see tutorial 16).
• support for multi-qubit circuits (new Circuit object; see tutorial 15).
• improvements to the DataSet object: you can now store "sparse" counts (where not every outcome is observed) and add meta-data to lines after a '#' symbol.
• ability to easily create LGST-only reports (see new example notebook).
• compatibility with plotly v3.0+ and cvxpy v1.0+.

There are also, as usual, performance enhancements and bug fixes.
