Update type checks to include NumPy numeric types

[peter-janderks]

isinstance(np.int64(1), int)) returns False for numpy 2.3.0 while it returns True for numpy 2.2.0 and earlier versions.
This caused AnonTaskStasts to raise an AssertionError.

Blergh this probably affects my code in so many places...

Thanks for the fix!

I didn't catch other lines that needed to be updated because I didn't actually run the sinter test.
pip install . didn't work on my apple device running Clang 16. This was fixed by updating to Apple clang version 17.0.0.
The tests passed on my device.

I didn't check python dev/doctest_proper.py --module sinter 🤦
