This PR fixes or closes issue: #1149

Motivation and Context

This card is very useful to control also a ceiling fan, the problem is that the current implementation does not provide the possibility to change the direction of the fan by the card itself; seems that also during the winter, the change of direction is one of the most used feature because of the comfort/efficency balancing that depends on the room occupancy. Currently to perform the action it is necessary to drill down in the detail card that is not so comfortable.

How Has This Been Tested

I tested the addition first with the local demo server, then I've loaded a js build directly into my "production" home assistant instance.
I tested it with a Cecotec 5400 that is supported via tuya integration.
