geom_col_name returns a single value for the name of the geometry column for the
WFS layer selected in the vicmap_promise object (e.g. SHAPE). This column will become the geometry column
when using collect(). feature_cols() provides a vector of all column names for the WFS layer selected in the
vicmap_promise object and get_col_df() returns a data.frame with the column names and their XML schema string
datatypes.
