Why this is unsupported since this is supported in Zstd
```
/**
* Return the original size of a compressed buffer (if known)

* @param src the compressed buffer
* @return the number of bytes of the original buffer
* 0 if the original size is now known
*/
public static native long decompressedSize(byte[] src);
