Changed to pychonet-2.0 and remove 'mitsubishi' branding.
This is the long awaited release to resolve many annoying issues people are encountering.
At the moment, you will need to copy across 'echonetlite' into your 'custom_components' and delete any mention of 'Mitsubishi' as the two codebases will clash. You can then add the integration using the GUI as per the instructions.
