Shutter Is Moving Property?

[FranzToepfer]

More a feature request than an issue:

Months ago I felt quite happy when discovering this approach to integrate my Somfy devices into iOBroker. With MQTT support everything there to basically open/close devices. Thanks for your work 👍

There is a minor improvement I want to ask for. For my iOBroker internal Node-Red based logic, would be great to get an information whether such an integrated Somfy device actually is moving.

• So as long as the requested target position not reached, a boolean information could be provided, that the device currently is in active operation (IsMoving=true).
• When reached requested position, property should be set back (IsMoving=false).

Any chance to get this extension realized?
