Add support for using Trigno/EMG as a StartReact input

[seasonedfish]

I thought of three different ways to implement this:

• create a class that takes in a TrignoClient
  • uses the TrignoClient to connect to sensors
  • implements its own start_stream, etc.
  • TrignoClient is still used to record data without timestamps
  • modify MultichannelBuffer to support skipping saving
  • pros
    • less likely that things go wrong
  • cons
    • additional complexity
• modify existing TrignoClient to implement protocols
  • fill Packet time attribute by computing the time from self.start_time and self.emg_sample_rate
  • pros
    • cohesive design
  • cons
    • may be more difficult to implement correctly
• use existing DelsysBuffer approach for all device managers
  • get timestamps using software timing when adding to the buffer
  • computed timestamps are not saved, do them in post processing

For this first attempt, I decided to go with the second option: modifying the existing TrignoClient to implement the protocols in bomi.device_managers.protocols.

Sounds good. good luck!
