New API in Blender 4.0, the first 'context' argument no longer exists.

…d .inputs

The latter was deprecated in favor of the prior.

This is no longer available from Blender 4.1

The 'import_mesh.ply' was replaced by '.wm.ply_import'.

…python

In 4.1 the node group replaces the prior implementation of auto smooth on object data.

…ender 4.1

Since Blender 4.1 the .exr depth outputs are one channel
instead of three channels. The imageio.v3.imread
using 'opencv' can't open single channel .exr. Thus
using nodes we create three channel image output
from the depth again.

This might be fixed in future versions of Blender, fix
to respect the file foramt 'Color' property (that's actually set to RGB)
was already merged into master:

Since Blender 4.1 'AgX' is the new default, but to yield semi-similar results we want to keep the default as 'Filmic'.

Adjusted breaking API changes, and adding
of the smooth by angle modifier - which is now
actually less prone to error.

Using the 'bpy.ops.modifier_add_node_group' would be superior,
but it doesn't work correctly in background mode.

So the 'bpy.context.collection' can be used afterwards. This worked
in Blender 4.1, but in 4.2 deleting the collection objects doesn't
make the root collection as the active in context.

This should fix the broken normals.
