Use Asset Library instead of the old Pose library in Blender 3.0

[Uwe Schmidt]

The new Asset Library is more versatile and way easier to use than the old Pose Library.

I was able to generate Pose Assets by using:

    bpy.ops.poselib.create_pose_asset(pose_name=name, activate_new_action=True)
    name = bpy.context.object.animation_data.action.name
    bpy.data.actions[name].asset_generate_preview()

in addToPoseLib().

I had one test file in which the preview generation failed, but with most of my test filed, all went well. I see no reason to use the old style pose libraries any longer.

By the way, the conversion from an old style Pose Library to Assets is buggy, the poses will change a lot. It’s probably better to re-import DAZ poses instead of converting the library.
