Add support for Blender 4.0

[Mysteryem]

Updated the addon to handle changes in 4.0 affecting this addon:

1. NodeTree socket inputs and outputs have been combined into a single interface.
2. PrincipledBSDF's emission input has been renamed from "Emission" to "Emission Color".
3. Armature/Bone Layers have been removed.
4. Bone Groups have been removed.

NodeTree socket creation and clearing has been moved to new functions that are defined differently depending on the Blender version, so that 4.0 and newer use the new NodeTree.interface API.

Getting PrincipledBSDF's emission input now uses the new name on Blender 4.0 and newer.

Showing/Hiding Bones in 4.0 and newer is now done by assigning to/unassigning from the "Visible Bones" Bone Collection. This isn't a great solution because all Bones must now belong to at least one other Bone Collection and all other Bone Collections each Bone is in must be hidden, but this results in behaviour closer to the original use of Armature/Bone Layers than only hiding the bones in Pose mode and not Edit mode.

Bone Groups have been replaced with extra Bone Collections in 4.0 and newer. The colors that were being set on Bone Groups are now set on each bone individually.

This seems to be the changes required to get the addon to support the recently released Blender 4.0.

I don't personally use this addon, but fixed it for a friend who does, so this patch was quickly put together and has not been well tested.

may you share the one?

If you mean the updated addon files, the link is at the top of the pull request to https://github.com/Mysteryem/XNALaraMesh/tree/master where the code (green button) can be downloaded as a .zip and installed as an addon.

Works perfectly in 4.0.2.0. Thank you! I never had any luck with this plugin before and had wasted several days rigging characters manually.

Hi! Is the plugin working with latest Blender 4.1 (stable) version? It's showing a error when I try to import model

Sorry, this PR was a one-off contribution that I decided to share after fixing it for Blender 4.0 for a friend of mine. I don't use the add-on, so I don't have any interest in maintaining it.

Getting the same thing :|

**UPDATE: I am not sure how to use GitHub honestly, all new to this, but I made a fix for it and will post it once I am off work tomorrow night.**

Here is a fix for the 'calc_normals_split' issue some people are having.
