wip: feat: panorama tiles

[meesfrensel]

Description

Implement tiling. Currently for panoramas only, but hopefully written in a way that it could be adapted easily to normal images too.

Fixes # (issue)

How Has This Been Tested?

Needs tests.

API Changes

Adds /api/assets/<uuid>/tiles/<zoom level>/<column>/<row>.
Should still add the tiling information to some endpoint. Maybe to /api/assets/<uuid>'s DTO. AssetResponseDto is it called?
