public CoroutineExceptionHandler
An optional element on the coroutine context to handle uncaught exceptions.
By default, when no handler is installed, uncaught exception are handled in the following way:
If exception is CancellationException then it is ignored (because that is the supposed mechanism to cancel the running coroutine)
Otherwise:
if there is a interface Job in the context, then Job.cancel is invoked;
all instances of interface CoroutineExceptionHandler found via ServiceLoader are invoked;
and current thread's Thread.uncaughtExceptionHandler is invoked.
