fantasy telescope idea
use rti1w as a base
* [ ] move rendering out of main.cpp
* [x] server waits for connection
* [x] client establishes connection
* [ ] client sends receiving port to server
* [ ] client application sends command to send image
* [ ] server receives imaging command
* [ ] server renders image
* [ ] server sends image data stream to client
* [ ] client application receives image
* [ ] client requests resend of lost packets
* [ ] client displays image
* [ ] client saves image to file
* [ ] server sends telemetry to client (what telemetry?)
* [ ] server compresses image before sending to client
* [ ] client specifies image parameters
