Add titiler service

[weiji14]

For dynamic raster tiling. https://github.com/developmentseed/titiler

Need to request new droplet first.

@willemarcel, I see that titiler is already defined in the docker-compose.yml here:

vbos-backend/docker-compose.yml

Lines 42 to 61 in cac0629

	titiler:
	image: ghcr.io/developmentseed/titiler:latest
	container_name: titiler
	platform: linux/amd64
	environment:
	CPL_TMPDIR: /tmp
	GDAL_CACHEMAX: 75%
	VSI_CACHE: TRUE
	VSI_CACHE_SIZE: 1073741824
	GDAL_DISABLE_READDIR_ON_OPEN: EMPTY_DIR
	GDAL_HTTP_MERGE_CONSECUTIVE_RANGES: YES
	GDAL_HTTP_MULTIPLEX: YES
	GDAL_HTTP_VERSION: 2
	PYTHONWARNINGS: ignore
	WEB_CONCURRENCY: 4
	ports:
	- "8002:8000"
	volumes:
	- ./data:/data # Optional: mount local directory with your raster files
	restart: unless-stopped

Do we need to do anything else here? Or just make sure that the endpoint is set up correctly?

@weiji14 this docker-compose is not being used. The one that is being deployed is https://github.com/developmentseed/vbos-backend/blob/main/deploy/vbos/docker-compose.yml

Ah ok, do we then add the titiler config to that vbos/docker-compose.yml file and deploy it to the same droplet/VM? Or would it be better to deploy to a separate droplet/VM? I'm not familiar with what's the best practice here, whether to have Django and Titiler on the same instance or one for each. If we need a separate one, lemme know so I can ask VBoS to set another one up.
