energenie.loop() written with FSK receiver connected to fsk_router

Router ready to be tied into a loop()

switch.py renamed as control_mihome.py, rewritten for new OO interface

Major tidy up of test harness and lifecycle methods

Moved test harnesses into separate _test.py modules

More representative synthetic data added to FSK receive test

Poked a synthetic switch on message down the MIHO005 receive pipeline

Started to flesh out the MiHome receive pipeline

Spec'ed interface for OOK decoder

Deprecated Messages due to import race with Devices. ...

Template messages (which are cloned with create_message) now in Devices.

Commissioned a tx path for MiHome adaptor Plus. ...

This is a temporary path, but it generates the correct message

LegacyDevice tx path commissioned end to end

Started to plan out the tx/rx pipeline for payloads and message buffers

Initial design of a message Router

Capabilities of devices turned into flags, with query method in base class

Mock registry store created, auto_create is working

Started to implement device classes code. ...

Simple mocking interface now working.

Method signatures for Registry sketched out

Python 3 now supported. ...

Logger now stores apparent power and real power headings.
Logger now stores temperature from eTRV in csv file

Tested FSK tx and rx on Pi, works fine ...

Tested both monitor.py and switch.py

Refactored so that we can create a tx-only switch loop tester. ...

This will be useful for integrating a new FSK transmitter without receiver
