Discuss and agree upon.

BE wishes to add purposeOfStay (work or tourism) as an optional field in the activity data.

• This is a field also currently required to be submitted to the Belgian national statistics bureau (currently directly submitted by hosts to Statbel)
• Some platforms have this as a required field to be filled in by guests, some have it optional

@VictorVanhulle could you clear out if this can be in the activity data?
