Tidyup: Rewrite logic for sending messages with a timeout.

[cianmawhinney]

AbortSignal became available in Node in versions 15/17ish, which can simplify wrappers around methods which may need to be cancelled/aborted/timed out.

Tidy up logic in https://github.com/cianmawhinney/visca-camera-controller/blob/master/src/camera.js#L767-L813 by using an AbortSignal instead of the Promise.race.
