Uncompresses the data in the specified input buffer into the specified output buffer. The inputSize should be set to the size of the compressed data in the inputBuffer. The expectedFullSize should be set to the original size of the data (before compression). Returns the actual size of the uncompressed data. Errors are reported by throwing exceptions.
