Compresses 'sourceSize' bytes from buffer 'source'

Compression is guaranteed to succeed if 'maxDestSize' >= LZ4_compressBound(sourceSize).
It also runs faster, so it's a recommended setting.
If the function cannot compress 'source' into a more limited 'dest' budget,
compression stops *immediately*, and the function result is zero.
As a consequence, 'dest' content is not valid.
This function never writes outside 'dest' buffer, nor read outside 'source' buffer.

compressedSize : is the precise full size of the compressed block.
maxDecompressedSize : is the size of destination buffer, which must be already allocated.
