- changes to CPX messages for streaming
- adds configurable streaming resolution
- adds missing viewer script
- removes read input from file, this was broken
(can be resurrected by fetching the depreciated frame streamer code from the sdk, but is not worth it)
- there are remaining issues: camera acquisition fails more often when
	a) wifi is enabled and not yet conncted
	b) the cluster frequency is high (75MHz seems pretty stable, 100MHz is still ok)
	c) the image is very dark (no clue why, but can almost be used for obstacle detection...)
- camera test is also working with 4.8.0.2 (only ASYNC capture though)
