To ensure payloads are delivered in time for the first subevent
in framed BIS, ISOAL now enforces a (configurable) margin of
the calculated time offset
Without this margin, it has been observed that a broadcaster
can end up consistently missing the first subevent in every third
event in a 7.5 ms ISO with a 10 ms SDU interval
The margin is a conservative 2 ms by default, but can likely be
set a lot lower for most implementations and HWs
