layer_xl_fgble2bg and layer_xl_fgble2bg support

[wangkai930418]

Hi,

Thanks for your strong contributions of making layerdiffuse into diffusers format.

I just wonder whether it is easy to support the layer_xl_fgble2bg and layer_xl_fgble2bg pretrained models as shown in the original github repo?

Thanks in advance!

Best regards!

Hi @wangkai930418, thank you for your interest for this project. FYI, I'm working on this, it would be nice if you can provide some sample input/output for verification
