Some colmap caches seem incomplete

[jytime]

Hi Team,

It seems that some COLMAP caches are broken for certain scenes. For example, in 4K/7f5223dfae59ed4cc2be125420b71f2b1e93556dd086cd091df55d9f30e51b99, we only have "database.db" instead of "cameras.bin database.db images.bin models points3D.bin". Could you help confirm does it mean this scene should be filtered out?

Best, Jianyuan
