+ Add `KLAYOUT_DEF_LAYER_MAP` for DEF/LEF mapping in klayout. `.lyt` is not sufficient to map a pin shape to pin and metal for example.  
+ Add `KLAYOUT_XOR_IGNORE_LAYERS` see <https://github.com/RTimothyEdwards/open_pdks/pull/347|RTimothyEdwards/open_pdks#347> (default: empty)  
~ Enable `QUIT_ON_XOR_ERROR` by default
