Switch default carrier of `genericSensorClient` device from `udp` to `fast_tcp` to avoid delays up to 0.25 seconds when a receiver is interrupted

[traversaro]

Switch the default carrier for two reasons (both detailed in https://github.com/robotology/yarp/issues/2814#issuecomment-1064943035):

• YARP blocks for 0.25 seconds whenever a UDP receiver is interrupted. The reason of this delay is not clear, but it will not be changed as the effect of such change are unknown due to Hyrum's Law
• In general it is not recommended to use a UDP carrier on a stream if there is no other reliable control stream
