support for cable car and others stopPlaceType

[Slusep]

In the StopPlaces model
https://purl.eu/doc/applicationprofile/netex-belgium/stopplaces-ap/
one of the properties of the StopPlace is stopPlaceType
stop place type
that's an enumeration list and I suggest to support
cablecarStation tu support current use of Namur télépherique and others future telepheriques (the one in Huy soon in function again and the 2050 project for the téléphérique of Liege)
It seems that we should also support
busTerminal
trainTerminal
metroTerminal
tramTerminal
especially in light of supporting deadruns
