pulseIn/pulseOut accuracy

[LeventErkok]

The implementation of pulseIn and pulseOut is inherently inaccurate.

The issue exists for both functions, as the Firmata communication overhead inherently adds inaccuracy to measurements. However, I've found that pulseOut is relatively OK for practical uses. However, pulseIn is unlikely to be useful for any sort of fine measurement (as would be required for distance sensing sensors, for instance), due to the extreme accuracy needed for such an application.

There's a proposal out there to add a pulseIn function to Firmata: https://github.com/rwldrn/johnny-five/issues/18

We should track the status there and start using it once it gets merged to mainline Firmata. (If ever.)

Resolved by using the custom implementation.
