Runs out of memory for large datasets

[MrPekar98]

When generating embeddings of larger datasets, say 30 GB, I will get an OutOfMemory exception. I run your container from Docker Hub on a server with 2 TB of RAM.

You can add the -Xmx flag when running the .jar file to increase the maximum heap size. For example, -Xmx500g.

@vemonet - could you take this?
