This will give us bidirectional tests, but requires changes since it changes the API

Xcode logs when adding NSLog(@"Elapsed: %.2f (duration: %.2f, test timer: %d, test usec timer: %d, now: %ld)", test_elapsed, test_duration, test->timer->time.secs, test->timer->time.usecs, now.tv_sec); to the test progress update code, looks like the test timer doesn't move:

It looks like stats_timer does move but the reference is not the current time. Time to actually dig into esnet/iperf@cde81d76 and understand what is going on.

a8e2ca6 updates iPerf3 to version 3.8.1, early simulator tests are looking good. There is an off-by-one error when updating the progress bar, it shows 100% progress before the end of the test.

Added more logging to understand why the UI completes before the end, it looks like we flag 100% progress before the end of the test, and start at 20% when we should start at 10% (this is a 10 seconds test):
