Add support for Project Aria datasets. (#2617)

* Add support for Project Aria datasets.

1) An export script for processing Project Aria datasets
2) Add support for Fisheye624 cameras
3) Add support for center-crop masking and sampling

Example commands for running nerfstudio on Project Aria data:

python scripts/datasets/process_project_aria.py --vrs_file=<path_to_vrs> --mps_data_dir=<path to MPS directory> --output_dir=<nerfstudio_data_dir>

ns-train nerfacto --data <nerfstudio_data_dir>  nerfstudio-data --orientation-method none

* Clean up type errors

* Fix formatting

* Fix linter errors, import, and use absolute file paths

* Add aria subcommand to ns-process-data

* Appease ruff

* Add Aria to docs

* Fix docs, add back import try/except

* nit: path.as_posix() -> str(path)
