    Move some layer variables to PDK, update io_place.py (#767)
    
    + `RT_{MIN,MAX}_LAYER` added to the PDK, relies on layer names
    + `FP_IO_{H,V}LAYER` added to the PDK, relies on layer names
    + `DRT_{MIN,MAX}_LAYER` optional override variables added
    ~ Minimum layer set to `met1` in the PDK, you have to enable `li1` manually
    ~ `GLB_RT_LAYER_ADJUSTMENTS` was moved to the PDK
    ~ io_place.py API redone in click, now also uses layer names
    - `FP_IO_{H,V}METAL` removed, will be translated to the new ones on-the-fly if they're in a user's config (for now.)
    - `GLB_RT_{MIN,MAX}LAYER` and its clock equivalents deprecated, will automatically be changed to the new ones on the fly
