ZSTD_compress() :
Compresses 'srcSize' bytes from buffer 'src' into buffer 'dst', of maximum size 'dstSize'.
Destination buffer should be sized to handle worst cases situations (input data not compressible).
Worst case size evaluation is provided by function ZSTD_compressBound().
Destination buffer must be already allocated.
Compression runs faster if maxDstSize >= ZSTD_compressBound(srcSize).
return : the number of bytes written into buffer 'dst'
or an error code if it fails (which can be tested using ZSTD_isError())
