Is the 128-bit version on the road map maybe ??

it could take sometime to develop, welcome to contribute

@leventov according to xxh3, the seed variant seems have to alloc an secret array.

it seems that the xxh3 (64bits and 128bits) use many internal state, e.g. (secret, acc, etc.), the performance is about 2x slower than xxhash64 in pure java implementation. The jvm would not take the advantage of x64 instructions and registers for this hash.
