text: Title: Alicevision Meshroom support for custom data format and reusable for gsplat as well?
  Body: **Is your feature request related to a problem? Please describe.**
  I'm running the SFM pipeline from Alicevision Meshroom, but I don't find a supporting np-process-data pipeline explicitly handle the Meshroom output. I searched issues and PR with "Meshroom" keywords and got nothing found. Since Meshroom is not a very poor quality calibration+reconstruction software. 
  
  Also, the new repo [gsplat](https://github.com/nerfstudio-project/gsplat/tree/main) has the example processing COLMAP format. Will this np-process-data pipeline become reusable for both repos?
  
  **Describe the solution you'd like**
  I verified Meshroom output in Blender including the camera extrinsic and intrinsics as well as the mesh location
  
  **Describe alternatives you've considered**
  manually have a code to convert the output from Meshroom to the nerfstudio is not difficult but could be integrated to the data preprocessing pipeline.
