[NumPy] Fix uses of functions deprecated in NumPy 1.25.

NumPy 1.25 deprecates a number of function aliases (https://github.com/numpy/numpy/releases/tag/v1.25.0rc1)

This change replaces uses of the deprecated names with their recommended replacements:
* `np.round_` -> `np.round`
* `np.product` -> `np.prod`
* `np.cumproduct` -> `np.cumprod`
* `np.sometrue` -> `np.any`
* `np.alltrue` -> `np.all`

The deprecated functions will issue a `DeprecationWarning` under NumPy 1.25, and will be removed in NumPy 2.0.
