Bug#1110196: ITP: meshroom -- A free, open-source 3D Reconstruction Software based on AliceVision

[Dima Kogan]

I uploaded the updated geogram and alicevision. Looking at making
meshroom run now. If you have some free cycles, can you package and
upload pyseq? I think that's the only missing dependency. If not, I'll
get to it at some point.

Thanks!
