Add dynamic timeout estimation for Ping360

`control_transducer` message [recommends a timeout of 4s](https://docs.bluerobotics.com/ping-protocol/pingmessage-ping360/#2601-transducer), but that's the absolute worst case. Some logical considerations are outlined in [this forum post](https://discuss.bluerobotics.com/t/ping360-sonar-stops-scanning/11091/6) as to timeout factors that are state-dependent, and could be dynamically reduced given knowledge of the requested message and the previous sensor angle.
