Update heatmiserv3 integration

[andylockran]

Breaking Change:

The current version of the heatmiser integration went out of date with the introduction of voluptuous. This has now been fixed, but it breaks the old config syntax slightly. See the updated docs for the new config format.

Description:

Update heatmiser component to latest version of the heatmiserV3 library, meaning less code inside HA, and more leverage on library.

Current version of the heatmiser integration went out of date with the introduction of voloptuous and it's taken me a long time to get the time to fix it. This fixes it, but breaks the old config syntax slightly. Submission to docs site has also been made, and references this PR.
