+ remove all unimported dependencies

Make it simple to switch between test and real schema

- plus blacken everything

Add stub function invoked when a received messages fails
to validate against the protocol schema.
Report on both invalid send and invalid received messages
from the example implementation.
Write received invalid messages to invalid directory.

The flask app doesn't receive updates live.
It just renders messages that have arrived in received.
I didn't want to get into writing javascript in this repo.

Render raw messages to the screen and via a simple api

Use mock schema installed from test fixtures
Encode the message as escaped JSON in the mock responses

This is still in separate processes so now need
to stitch those together into a single entrypoint
that runs both the send and receive operations

implement sender to transmit files from folder
