Updates to setup.py file for modern pip installations

[appy2806]

The current setup.py file uses setuptools.find_packages() only looks for directories that contain an __init__.py file. Looking at the standard structure for theproject:

streamframe/
├── setup.py
└── streamframe/
    └── streamframe.py  <-- No __init__.py here!

I recommend using the "Module" structure, given its a single .py file. Something like this:

from setuptools import setup

setup(
    name='streamframe',
    version='0.1.0',
    py_modules=['streamframe'],  # Use this instead of find_packages()
    install_requires=[
        'jax',
    ],
    # ... rest of your setup ...
) 

This update will ensure that the module is pip installable in the correct format.
