Fisheye support

[gradeeterna]

Hi, I posted this request in the original repo, but just saw you've added loads of nice features here!

It would be great if this tool worked with Metashape's fisheye camera type, now that Instant NGP supports OpenCV fisheye.

Nerfstudio's Metashape import was recently updated to support this, in case it helps:

https://github.com/nerfstudio-project/nerfstudio/blob/f015245ca4be13b1d3778e4d139c1f1590013757/nerfstudio/process_data/metashape_utils.py#L15

Currently using Colmap to align fisheye images, but it's painfully slow compared to Metashape!

Thanks!

Hi @gradeeterna thanks!

Metashape is on my list to get working. Thanks for the idea, I'll have to look into it but it should be easy to add.
