- Corrected data types for allocation made in Cython which were responsible for test failures with NumPy 2.0 on Windows.

This is a bug fix release updates `mkl_random` to support NumPy 2.0

Transition testing suite to pytest to enable support for Python 3.12

Change to fix build on `mkl_random` with `clang` with new build system introduced in v1.2.3.
