Add Websocket Camera Streaming (#529)

* WIP adding second websocket handling for cameras

* just more WIP

* even more wip. Most java-side framework completed, but not yet debugged

* IT LIVES. Still needs lots of cleanup. But we're transferring and displaying data!

* moved down an architecture layer. Improved multiple-camera handling

* Additional WIP to help improve smoothness and performance, though not yet tested

* bugfixes galore

* tweak compression

* spotless

* more tweaks for handling slow/intermittent streams

* wpilibformat maybe?

* clang-format maybe?

* WIP - adding thinclient. I don't like it yet, it should be more auto-generated than it is.

* thinclient formatting fixups

* Reduced amount of empty send data by limiting to only one stream per client (which is all we really need). Framerate is up slightly, overhead is down.

* bugfixes, faster streaming, better mjpeg compression settings, thinclient working

* spotless and formatting

* cmon wpiformat....

* re-added mjpg streams

* added a loading GIF to imporve the feeling of responsiveness

* formatting

* urlparams and built-in thinclient

* wpiformat

* prevent wpiformat complaints

* Removed uint8 array and base64 conversion from client side

* Synced up js implementations for ws streaming

* formatting/spotless
