[enocean] D2-50 change units of supply and exhaust air fan flow rate

[lovery]

Description

Change the units of the Supply and Exhaust Air Fan Flow Rate from m^3/m to m^3/h
Here is a screen shot of the documentation:

Something to keep in mind for someone with such device - using different item types could show the values differently like:
Before the change:

• with item type Number:VolumetricFlowRate the value was in l/h but it was using l/min suffix - which was incorrect.
• with item type Number the value was correct and the workaround is to add [%.2f m³/h] to the label to show the units correctly.

After the change:

• with item type Number:VolumetricFlowRate has the correct value in l/min and if you have to change the suffix you coulld use [%.2f m³/h] in the label.
• with item type Number the value is also correct and you could add [%.2f m³/h] to the label and unit="m³/h" in the bindingconfig section in order to show the units.

Testing

Here is a jar file for 4.x.x to test and for 5
