Add the ability to pre-register a layer LEF layer mapping in LefImport.
In some case, the LEF technology definition do not defines all the CUT and ROUTING layers, so there are *less* than in the Hurricane complete one. This may cause a discrepency in the mapping table between Hurricane and LEF. Thus we modify LefImport::addLayer() so that we can specify a LEF type and load it into the mapping table the missing ones. This case did occur for an undeclared *contact* layer.
