[Enhancement] Copy seed to converted world

To Reproduce Steps to reproduce the behavior: Convert any Bedrock world to an Java world and load new chunks Expected behavior Loads all the chunks in a normal matter as it should be and no chunk corruption

@gentlegiantJGC , is it possible this could be implemented using the "blending_data" trick mentioned in #476?

Yep
Here's the world converted from Bedrock to Java

And here's the same world where i manually tagged bedrock chunks with "blending_data".
But I also had to delete all the other chunks to force the game to regenerate (and blend) them.
