Test gaze master inputs

[okawo80085]

We need gaze master tested, imo VRChat is the most popular choice now (they added eye tracking to avatars through their new API), for us to use gaze master with VRChat we'll need a new plugin for that, shouldn't be too complicated... hopefully...

@SimLeek check out VRChat's docs on the new API they use:
https://docs.vrchat.com/docs/osc-overview

[SimLeek]

The actual protocol, I think: https://protocol.vmc.info/english

After reading the VRChat site a bit, I don't think they actually have any standards for communicating to the avatars, and the avatars will just accept whatever data you program them to accept.

@okawo80085 Is this done? We have some standard OSE paths set up, a python lib for testing them, should have a vrchat model for using them soon?, and the gazemaster plugin actually just has to get eye info from hardware and send it to OSE, without necessarily interacting with steamvr at all.

This is technically done, but only with the default gaze master plugin we ship as an example, ideally i want to keep this open until we get the VRC plugin running, but at this point its not in the way of our current release.
