Get the uncompressed byte size of the given compressed input. This
operation takes O(1) time.

@param compressed input data [pos() ... limit())
@return uncompressed byte length of the given input
@throws IOException when failed to uncompress the given input. The error code is
{@link SnappyErrorCode#PARSING_ERROR}
@throws SnappyError when the input is not a direct buffer
