Panorama depth estimation has empty hole

[YoujunZhao]

Thanks for your great work. Currently, the pipeline only supports depth estimation using the UniK3D model. However, UniK3D tends to produce large empty regions (in the upper and bottom portions) of the panorama depth, which impacts the quality of 3D Gaussian Splatting reconstructions that rely on this depth data. I wonder if the panorama pipeline support more depth estimation models?

Thanks
