PbHub + Ultrasonic.IO

[robot_alf]

Hello M5 engineers!

Could you please add a simple function to the PbHub for ultrasonic sensors? Something like this - https://github.com/ErickSimoes/Ultrasonic/blob/master/src/Ultrasonic.cpp
Because I can't to it through blocks or python, it's microseconds between send a receive an impulse.
