Allow passing custom name for miotdevice.set_property_by

[rytilahti]

This allows passing a name to use instead of the hardcoded set-{siid}-{piid} as did for miotdevice requests:

dev = MiotDevice(...)
dev.get_property_by(111, 222, 333, name="dummy-name")

will cause request did to be set to dummy_name.

{"did": "dummy-name", "siid": 111, "piid": 222, "value": 333}

Breaking change
The set_property_by's value_type is converted to keyword-only argument.
