1. Wouldn't it be simpler to merge feature/types.h into util/types.h?
2. The pycolmap CI is down because liblzma is now down following the vulnerability discovered in xz: [liblzma] port uses compromised version microsoft/vcpkg#37839 Best is to wait that this gets fixed in vcpkg.

1. I would like to avoid shoving more types into the global util/types to avoid a global knot in the dependency graph.
2. Thanks, I'll make a vcpkg update in a separate PR first.

liblzma is now back online (no need to update VCPKG) but freeimage now fails in all VCPKG-based pipelines.
