fix: impl path retrieving helper functions (#394)

[StevenJacobs61]

Features

• Inited producer when start_recording each time.
• Persisted recording context within robot instance
• Cleaned up producer channels which had been stopped
• Created sequence numbers for data chunks so that the stop recording didn't cause unprocessed valid chunks to be dropped.
• Improved channel state.
• Created thread-safe socket use (mark)

Bugfixes

• Channels were closing and dropping data from one recording to the next
• Stop recording caused unprocessed valiid (chunks sent before stop recording but just not processed yet) to be dropped
