Packaging for Accessibility

[tnaumann]

Given the mix of Python and non-Python dependencies (java, mactex), it would be difficult to host this on PyPI. Nevertheless, it would be useful to package in such a way that it can be more easily called as a command-line executable in order to improve ease of use. Similarly, it would be useful to create a GitHub action that runs this tool against a repository in order to generate the required output.
