add a python package for speech dispatcher python bindings

[lilmike]

Is your feature request related to a problem? Please describe.
With almost all python programs wanting to run from a virtual environment these days, having the ability to pip install speech-dispatcher would be extremely helpful.

Describe the solution you'd like
Add a python package for the speech dispatcher python bindings, and release it on pypi.

Describe alternatives you've considered
The only other real way to get this to work is to copy the binding from the host system to the virtual environment, which is much more messy and cannot easily be managed by python tooling (uv, pip, etc).

Additional context
Essentially, to support the modern python application requirements of each having their own virtual environment, a speech dispatcher python package needs to be built and released on pypi. At the very least the ability to package it into a python package needs to exist, even if someone else takes care of building and hosting the package.
