Networking needs major overhaul

[yameatmeyourdead]

The current implementation of networking leaves much to be desired. Need to be able to transfer simple primitive data types for metadata transfer (e.g. power usage of ROV, camera statuses) as well as more complicated data transfers such as generated images (from camera or drawing software) most likely to be numpy arrays. The current implementation of both systems uses an outdated threading model that should be overhauled to use a thread pool or just be single-threaded.
