Proposal: amenities in locations

Hi,

Another worked up proposal based on our recent community group calls. This
one defines a list of the most common amenities that participants are
likely to be interested in when visiting a location

https://github.com/openactive/modelling-opportunity-data/issues/70

Again, please find any comments or feedback, I'm keen to include this in
our 1.1 releases.

Cheers,

L.
