Support for adding a Chunk (not EmptyChunk) to an EmptyRegion

[brychrwolf]

Hello,

I would like to use your project to iterate over all mca files in a folder, and only save chunks which match a list coordinates. The problem I have is that there is no way to pass the output of getchunk, to setchunk as you know, Chunks are not EmptyChunks.

No errors actually occur until I call save which tries to access sections... which don't exist the same in both types. I tried iterating over over all blocks in a chunk, and adding them to an EmptyRegion with set_block, and its almost okay, except some things are invisible (like signs).

Is there any way you could make it possible to pass add a Chunk to an EmptyRegion and then be able to save that to a file?
