split Features and Tiles endpoints in the Factory

[vincentsarago]

let's have a Endpoints().register_ogc_features() and Endpoints().register_ogc_tiles()

then we can do

    def __post_init__(self):
        """Post Init: register route and configure specific options."""
        self.register_landing()
        self.register_conformance()

        if self.with_ogc_features:
            self.register_ogc_features()
       
        if self.with_ogc_tiles:
            self.register_ogc_tiles()
