CoreConfig how has a playback mode option which can be set to reprocess
or read.
Setting it to reprocess means that all derived signals are reprocessed
during playback, in this case the PlaybackEngine only plays back the
signals whose source is set to "origin"
Setting it to read means that all derived signals are playedback from
the recorded buffer, this whill be the preferred mode once offline
processing is set up which will allow for more complex data processing
offline once a recording is completed, which would require the read
playback mode as it wouldn't support realtime processing as reprocess
does
Implemented handshake in json server and handoff to endpoint
Endpoint handles connector handshake accept/decline then launches both
its IO threads alongside its heartbeat thread which contains simple
timeout logic, timeout calls connection handles to close, subsequently
killing the endpoint
Isolated the JsonServer to server.py inside protocols/json
Added specific errors for server startup timeout and server startup
failed
Refactored errors for Core to CoreError generic and refactored
StateError to CoreStateMismatchError derived from CoreError
Completed the initial implementation of the JsonServer class, handling
the worker thread that runs the async task, as well as the connection
handler callback
The current handler awaits readline to cleanly exit when the connection
is closed, no data ingress is happening yet
Next steps include gating the start procedure to wait for everything to
start proprerly in order to avoid having start exit early and async
tasks crashing later
