This reads the unknown packet data, just throwing it in a byte buffer. This allows us to read the rest of the segmenets in the packet, and fixes parsing. Note that this still log spams with "wrong size" as we can't determine the size of the unknown packet ahead of time. This is easy to fix, but it's not a high priority yet. Fixes #73
