Realigned camera parameter extraction

[JunhyeongDoyle]

Hello,

First of all, I want to express my gratitude to everyone contributing to this project. I've found it incredibly helpful in my work.

I am currently working with custom LLFF data for training and am interested in whether there's functionality to export realigned camera parameters into a file for further analysis and other uses.

Question 1: Does the current implementation support exporting realigned camera parameters to poses_bounds.npy file when training with LLFF data?
Question 2: If this feature is not supported, could you recommend an approach for implementing it? For example, I am looking for advice on modifying or adding to certain parts of your code.

Thanks.
