fix(vrtsim): Reduce OS scheduler pressure caused by vrtsim timing thread (#235)

Increase the usleep to 20 uS to reduce the pressure on the OS scheduler.
This reduces the number of context switches and increases performance.
The value 20uS is approximately half a symbol in mu1 and shouldn't cause
too much extra delay.
