Load 3d animation node upgrades

### Feature Idea

Hey Comfy Team, I have been testing the new load 3d animation node (comfyui nightly latest) and it needs some things that are really important IMO. It needs focal length for the camera so we can set it to say 24mm for a wide shot. It also needs to have a boolean to allow the user to either use the camera information within the FBX file or move the camera on their own while recording. I tracked down the files needed to modify it and they are in the precompiled code for the front end which is a huge mess to try and sort out for those of us who are adding to and augmenting the code. If you could work these features in that would be dope. I noticed an orthographic camera mode which is definitely a step in the right direction.

### Existing Solutions

Just using blender itself is definitely a solution for this, but I think there are some awesome use-cases where these nodes can save a lot of time if they have a few more bells and whistles.
