Release 0.6.1

[pablolh]

Added

• Linux arm64 Python wheel and Linux arm64 test workflow (GCC-Release)
• "classical not" gate is back
• "state" section in JSON now contains a new entry "norm" which is the square of the modulus of the complex number
• C++ integration test
• All gates can be controlled (including prep, measure). This is not new but was accidentally removed in 0.6.0.
• New Python API execute_string and execute_file without having to create qxelarator.QX() and returning user-friendly Python type

Changed

• Fixed README
• "results" section in JSON contains integers instead of floats (those integers being the number of occurences)
• In relation to previous point, "results" only relates to measurement register averaging, and no longer to quantum state when doing a single shot. For that, use the "state" section in the JSON.
• Output float precision is 8 decimals instead of 6

Removed

• Most Python tests - already covered in C++ integration test, and they didn't check much anyway

Good afternoon This adds back classical not gate but not yet error models Also worthy to note the change to integers for measurement register averaging, discussed with Maarten
