Title: Handle proj4 bare parameters with string values

This fix covers the case where routing projections through pyproj, which represents proj4 bare parameters (e.g., ```no_defs```) as ```key=``` instead of simply ```key```. Simply checks for boolean types as string values (e.g., ```'True'```) prior to attempting to type-cast values.
