Reverse-engineering the Oculus Link / XRSP protocol.

| 0x01 | Byte | Topic |
| 0x02 | Byte | Length(?) |
| 0x03-? | ? | Topic Data(?) |
Topics are essentially IDs for various datatypes that XRSP has, they are 6-bits(?) in length and are masked to "0x3f" (I think). Certain topics are also encrypted, it is currently unknown as to how they are encrypted. When an XRSP device is connected, the first topic that the device sends is "0x01" and then the server may respond with the next appropriate topic.
