Lera Elvoé b55a462945 Add OBS and Twitch nodes. Improve UX significantly. Rework groups from the ground up with a new instancing feature. Open to the public. (#18)
After months of work and over a hundred commits on this repo alone (not to mention the old, half-working repos on GitHub), StreamGraph is finally ready to be shown to the public, even if in an incomplete state.

This PR is a culmination of numerous design discussions, re-writes, and hours spent by both @Eroax and myself.
