Port streaming/live plotting/file saving from NDTP to protobuf

[polymerizedsage]

We have switched from NDTP to a protobuf-based wire format for streaming data from Synapse devices. The new protobuf format is documented here. The code for streaming data using the CLI needs to be ported to use this new format. This includes:

• Receiving and parsing protobuf messages from StreamOut or Taps.
• Saving the proto messages to disk.
• Live plotting received proto data.
• Offline plotting files using the saved protobuf messages.

@polymerizedsage looks like #121 and #122 are a complete fix to this issue?

@gilbert-sci can close if these features are all in!
