Converts the stops table to a POINT sf object.
convert_stops_to_sf(gtfs, stop_id = NULL, crs = 4326)A GTFS object, as created by read_gtfs().
A character vector including the stop_ids to be converted.
If NULL (the default), all stops are converted.
The CRS of the resulting object, either as an EPSG code or as an
crs object. Defaults to 4326 (WGS 84).
A POINT sf object.
