Curate licenses in tapor data
There is a problem with tapor data regarding licensing: they only have information about license type, not the specific license.
We take the information as it is in tapor (in a separate property @license-type@).
However ideally, we need information about the precise license under which given resource is available. This requires a separate curation work, where we revisit the tools and fill the specific license.
