When importing a VRM1 avatar, Physics Asset isn't included

Unreal Engine v5.4.4
VRM4U v20241007

Describe the bug
When importing a VRM0 avatar, a Physics Asset is included.
But when importing a VRM1 avatar, the Physics Asset isn't included.
On both imports, the No physics asset setting is disabled (default state).

The VRM Spring Bone physics still works correctly in VRM1, so I'm not sure if the Physics Asset is actually used by VRM4U.
Nevertheless, including the Physics Asset is still very handy, for scenarios where you need a Physics Asset (e.g.: using Chaos Cloth in the VRM avatar).

Hi.
How would you like to use that PhysicsAsset?
VRM0 generates a PhysicsAsset, which is useless in most cases.
The functionality has been retained just in case, but will remain as it is unless there is a specific reason to change it.

I'll add Chaos Cloth simulations to my avatar, so the PhysicsAsset will be used to control the Chaos simulation collisions.

I'm not sure if the generated PhysicsAsset works properly with Chaos Cloth (I haven't tested it yet).
But at least, it would make a nice base (already adapted for my avatar) for tweaking and creating my own PhysicsAssets, instead of having to create one completely from scratch.
