  Use above functions alternatively.
  ZSTD_nextSrcSizeToDecompress() tells how much bytes to provide as input to ZSTD_decompressContinue().
  This value is expected to be provided, precisely, as 'srcSize'.
  Otherwise, compression will fail (result is an error code, which can be tested using ZSTD_isError() )
  ZSTD_decompressContinue() result is the number of bytes regenerated within 'dst'.
  It can be zero, which is not an error; it just means ZSTD_decompressContinue() has decoded some header.
