Potential Fix for Folders Not Working

[camdrit]

This should partially address #13 specifically in regards to folders not working. Essentially I added a function to recursively get the parent path for nested nodes and additionally added a condition for layer.isGroupLayer to recognize folders.

Tested to work on layers nested multiple groups deep, would be great if someone could review a case with object layers as these are not used by me in my current project.

Other than that, feedback/cleanup on my implementation is definitely desired....running on very little sleep after trying to find a good solution for exporting Tiled maps to performant Godot scenes (thanks very much for this extension, it works fantastically in this regard!) so this may look messy.

There seems to be at least one remaining parent: ".", that likely needs to be adjusted to call getLayerParentage, just after } else if (layer.isObjectLayer) {.

Other than that the change seems reasonable, but I haven't tested it,

I think this is outdated and should be closed.
