1.5.7

Project infrastructure:

• Enabled CI builds for Python 3.12 (#182).
  • Updated cibuildwheel version used by CI to 2.16.
  • Added Python 3.12 to meta-data classifiers in pyproject.toml.
  • Added Python 3.12 to tox.ini, removed Python 3.7.
  • Only use custom meson install script to byte-compile installed Python modules if meson version <= 1.2.0.
  • Updated latest Python version mentioned in windows install docs.
• Updated requirements-dev.txt with pip-compile (#183).

Fixes:

• Fixed linting errors in send_all.py example (#184).

• Fixed (no)gil/except declarations on MIDI in callback and MidiOut.sendMessage (#185).

  The GIL is acquired in any case for MIDI in callback and C++ sendMessage call, since Cython needs to check for exceptions.

  Suppress related Cython compilation performance hints.

  Also remove wrong statement about the GIL being released in docstring for send_message.

• Fixed errors and check for empty message correctly when passing an iter- or generator instead of a sequence to MidiOut.send_message (#186, #188).
