v1.0.0: Rename arrow to stochastic_arrow

• Renames arrow module to stochastic_arrow to avoid name conflict (#51)
• Add test_fail_stdout to test_arrow.py to check console output upon simulation failure
• Add Github Actions pytest for Python 3.9-3.11 on Ubuntu, Windows, and MacOS
• Tweak a few types to avoid warnings across all platforms (particularly Windows)

release 0.5.2

• Update to Cython 0.29.34 which should provide Python 3.11 compatibility. (Cython 3.0.0 is now in beta.)
• Add arrow.pxd to work around a Cython 3.0.0 bug.
• Stop using deprecated numpy.distutils to avoid warnings and prepare for its removal in Python 3.12.
• Make test_arrow.py --plot compatible with Python 3.
• Fix PytestReturnNotNoneWarning warnings from pytest 7.2.0.

v0.5.0: Fixes a hang bug

• Fixes a bug where evolve() would hang in an edge-case (Issue #48), adds the arrow_hang unit test, and makes the code more robust to some other potential bugs.

v0.4.4 Feature: Can pickle StochasticSystem instances

Pickling instances of StochasticSystem now includes the state of the psuedo-random number generator, so unpickling should fully restore that state.
