Unique identifier for icarAnimalSortingCommandResource.

[Harry-UA]

icarAnimalSortingCommandResource doesn't have a unique identifier for the command. If a system allows multiple sorting commands per animal, there is no clear way to update/delete an existing sorting command due to the lack of a unique identifier. Should a unique identifier be added or is there another solution for this?

A workaround would be to use meta.sourceId (and set meta.source for consistency). However, this is not as clear as allowing an identifier, and many other resources also have identifiers (e.g. animal.identifier, event.id).

We agreed to add id to the resource.
