Resaving a terrain model containing sample chunk header doesn't keep its properties #74

The code in question.

Is this intentional or a mistake? I'm making an issue since I'm not sure how I should be implementing it.

Thanks for pointing this out! Yeah, this was a mistake on my part. It seems terrain models each have a single "root node", and sample chunk nodes can be utilized to apply SCA parameters to that node just like in skeletal models. I wasn't accounting for this in my code, so SCA parameters were skipped on read, thus causing them to be missing when resaving the file.
