Get attributes about the banks of each cross section in a dataframe of cross section points Given a set of cross section points with point_type column, return a dataframe of the unique hy_id/cs_ids with the following calculated columns: "bottom", "left_bank", "right_bank" columns which are the Z values of the "lowest" bottom point, and the "highest" left and right bank Z values, respectively. And a "valid_banks" column indicating whether the hy_id/cs_id set of cross section point has at least a signle bottom point with at least 1 left bank point AND 1 right bank point that are above the lowest "bottom" point.
