Fix test failures

[lymichelle21]

Address tests failures outlined in #181

• Add optional dependencies for tests flag
• Add dependency constraints on numpy and numpoly when using tensorflow-macos (latest version 2.16.2)

tensorflow 2.16.2 requires numpy<2.0.0,>=1.26.0; python_version >= "3.12", but you have numpy 2.2.2 which is incompatible.

• Use progpy import instead of prog_algs since they are merged in one package as noted in ProgPy v1.6 released #120
