Bugfix for outdoor sensors

This fixes a breaking change to the outdoor sensor that was introduced with the rolling changes to mitsubishi_echonet v5.0.
The library is now version 0.5.1 so the custom component is now version 2.1.2.

Updated to support 'mitsubishi_echonet' v0.5

This is a release to hopefully address potentially issues related to the non-availability of 'Outdoor Temperature' ECHONET values for some systems.

This was a feature/bug that was introduced in v0.4.1 of the 'mitsubishi_echonet' library which I think is adversely impacting the 'update' routine in the Home Assistant component for some users. This feature/bug was not present in v0.3 of the library which is why it was probably working for most users on prior release 2.0.1 of the custom component.

The underlying bug has been addressed in v0.5 of the 'mitsubishi_echonet' library.

If users are still having issues, please add the following debug logging to your 'configuration.yaml' file:

logger:
  default: warning
  logs:
    custom_components.mitsubishi: debug

Look for the following details in the logs:

2021-06-12 08:46:08 DEBUG (MainThread) [custom_components.mitsubishi.climate] ECHONET lite HVAC X.X.X.X component added to HA
2021-06-12 08:46:08 DEBUG (MainThread) [custom_components.mitsubishi.climate] HVAC has the following get properties:

That will give me a hint as to what any potential issues are when compared to my own setup.
