Fix test failures

[lymichelle21]

Address tests failures outlined in #181

• Remove tensorflow-macos due to compatibility issue with numpy>= 2.0.0

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.

• • Alternative would be to add dependency constraints on numpy and numpoly when using tensorflow-macos (latest version 2.16.2)

datadriven = [
    "tensorflow; platform_system!='Darwin' or platform_machine!='arm64'",
    "tensorflow-macos; platform_system=='Darwin' and platform_machine=='arm64'",
    "numpoly==1.2.12; platform_system=='Darwin' and platform_machine=='arm64'",
    "numpy<2.0.0,>=1.26.0; platform_system=='Darwin' and platform_machine=='arm64'"
]

• Add optional dependencies for tests flag and remove test_requirements.txt
• Use progpy import instead of prog_algs since they are merged in one package as noted in ProgPy v1.6 released #120

Everything worked on my computer and completed code review. Good work
