Does not return correct values for new Particle mesh devices.

When using the RHT03 sensor and this library for the new Particle Mesh devices, the return values are not consistent. There is a thread in the Particle community forums about the issue here:

It is possible that the use of noInterrupts() and interrupts() may cause unintended problems with timing on the Mesh devices.
