Feature: Tap API in simulated broadband source

[arminvoid]

Summary

This is a change for #125. I wasn't sure if there's another simulated/virtual SciFi device that I should write the example against so I went ahead and updated the simulated broadband source in this repo to stream data over tap API. Also migrates legacy ndtp type to BroadbandFrame.

Testing

Run simulated device

synapse-sim --iface-ip 127.0.0.1

Run Client

1. script

python synapse/examples/tap_example.py

2. CLI

@arminvoid -- thanks for your interest. There are a few things we need to set up before we can actually accept community contributions, but it's probably time. @morninj @gilbert-sci
