AR: fastpath optimizations

Browse Source 
Some optimizations in FASTPATH mode, to ensure that audio processing takes places as soon as new samples are arriving:
* raise fftTask prio to 4 (above async_tcp) - to ensure that other gimmicks (MQTT, IR, alexa, live preview (ws), json API, or web UI) cannot cause delays by preempting audio.
* changed the "be nice" condition in AR::loop
