The lib includes a wait on SCL high, this is either an event or a polling loop, dependent on implementation.

If this is called on a system where the pull up isn't present then the project can hang forever - not ideal.

If would be better if this error was detected and reported to the developer.

This could be done with timeouts or a simple check for pull-up present at init time.

Real world use case is running USB Audio project on a custom board - we ideally don't want it to hang.
