`ResourceURL`’s `format` is now used to determine if a layer is a vector layer. `get_layer_configs()` is now `get_vector_layer_configs()` and only gets the layer configs for layers whose `mime_type` is `application/vnd.mapbox-vector-tile`. `data_file_uri` is now used for the data in the mapfile. Moved reading the `MAPFILE_TEMPLATE` so that `template_string` is assigned before handling vector layers. Haven’t yet addressed the issue of single vector layers potentially becoming multiple vector layers in MapServer configuration.
