latest version of Starlette (fastapi>=0.94) breaking changes

[vincentsarago]

in starlette >=0.26 there was an introduction of a breaking change for the url_path_for url_for methods which now returns URL class instance instead of a string : encode/starlette#1385

this breaks TiTIler in place like

titiler/src/titiler/core/titiler/core/factory.py

Lines 780 to 797 in 4975fc3

	for (key, value) in request.query_params._list
	if key.lower() not in qs_key_to_remove
	]
