Textures are not fully matched

Hello, I'm trying to convert [this collada model](https://drive.google.com/drive/folders/1srUFk2jR-qzfLuqBvqQRcp_gERyrBUwS?usp=sharing) into GLB.

I used the command below to convert it (in Ubuntu):
```
COLLADA2GLTF-bin -i 4833_9.dae -o 4833_9.glb -b
```

They were converted without any error, but when I load the output GLB into Cesium.js (version 1.53),
It seems that some area of the model are not matched to the textures and shows in black.


In order to make sure the original collada file is valid, I've also load the model in Google Earth, and it looks normal.


I'm not sure which part in the whole converting process goes wrong.

Thanks in advance!

Start by reproducing the COLLADA2GLTF-bin command with the linked 4833_9.dae model in Ubuntu, then inspect the generated GLB in Cesium.js 1.53 and compare it with the source shown in Google Earth. Done means the converted model displays all areas with the correct textures and no black regions.
