DO NOT USE - Only for test in real environment.
This release implements a new VTherm type. This new type allows the VTherm to control directly a valve through a number entity (or an input_number).
See #131
At each cycle of calculation, VTherm calculate the percentage of opening the valve should have (between 0 and 100) and calls a service to change the number (or input_number).
A new entity have been provided to display the value sends to the valve. The entity is named: valve open percent.
To use it, just configure a new VTherm (or update an existing one) and gives the number entity to control. Up to 4 valves could be controlled with one VTherm.
Because I cannot test in a real environment, I need some real tests before publishing the release.
