Adding glomap support to ns-process-data, works with COLMAP 3.8!

[AntonioMacaronio]

Problems and Background

• GLOMAP is orders of magnitudes faster than COLMAP. On average, it finds camera extrinsics, intrinsics, and other distortion parameters and such 100x faster than COLMAP, and it would great to support this in Nerfstudio and already has been requested

Overview of Changes

• Adding a GLOMAP toggle in ns-process-data script, which uses the GLOMAP mapper

TODOS:

• need to still fix the funny nerfstudio formatting with the colmap/sparse folders
