Added Sphinx documentation

[dtemir]

Description

This PR adds a sphinx directory that takes the available documentation in docs and converts them into an online website documentation.

It also adds a new GitHub workflow to automatically deploy any changes to a gh-pages branch to keep it live on GitHub Pages. It is currently deployed on my fork, under https://temir.dev/labgraph/.

But once merged to this repo, you can set it up to work with a URL similar to https://github.io/facebookresearch/labgraph

Fixes #46

@jfResearchEng if you decide to merge it and put it on GitHub pages, you need to go to the repository Settings -> Pages -> make Source point at gh-pages, root to make everything work.
