Implement quick fix for negative energy readings and add known issues to README #21

Whenever a counter overflows, pyJoules will report a negative energy measurement.

As a quick fix, I propose adding the corresponding max_energy_range_uj to negative energy measurements.

If a counter overflows twice during a single energy measurement, the reported energy will be max_energy_range_uj less than the expected value.

I also added this information to the README.
