HUF_compress():
Compress content of buffer 'src', of size 'srcSize', into destination buffer 'dst'.
'dst' buffer must be already allocated. Compression runs faster if maxDstSize >= HUF_compressBound(srcSize).
Note : srcSize must be <= 128 KB
return : size of compressed data (<= maxDstSize)
@return : size of compressed data (<= maxDstSize)
Special values : if return == 0, srcData is not compressible => Nothing is stored within dst !!!
if return == 1, srcData is a single repeated byte symbol (RLE compression)
if HUF_isError(return), compression failed (more details using HUF_getErrorName())

'dstSize' must be the exact size of original (uncompressed) data.
Note : in contrast with FSE, HUF_decompress can regenerate RLE (cSrcSize==1) and uncompressed (cSrcSize==dstSize) data, because it knows size to regenerate.
