Feature Request: Support for Geo-referenced Point Clouds in xrdslam

[Raghavrs1999]

Hi OpenXRLab team,

Thanks for the great work on xrdslam!

It would be very useful to add support for geo-referenced point clouds by integrating GNSS or positioning data. This feature would enable exporting point clouds in global coordinate systems (like WGS84), making the output more practical for mapping, surveying, and robotics.

Adding this capability would make xrdslam more robust and valuable for real-world applications.

Thanks for considering!
