This is a minor change to SdReader.h and SdReader.cpp that fixes a bug in reading the size
of large SD cards. I imagine most code that uses the library doesn't depend on this function,
but the SdReadTest unit test does.
See the equivalent code in https://github.com/greiman/SdFat/blob/master/src/SdCard/SdCardInfo.h#L326
I ran all examples in the WaveHC library. I discovered this when vetting my change for fixing issue #3 and decided to break it out into a separate PR.
Before this fix, the card size reported by the test was insanely large, probably caused by the top bit being set in a 16 bit int implicitly used when 'mid' is not cast:
After this fix, the SdReader test reports a sane card size:
