Simplify getting the download URL(s)

[Aklakan]

dcat search --jq datasetid yields a json description of the matches, and all downloadURLs can be obtained using

dcat search --jq org.limbo:train_3:0.0.1 | jq -r '.[].distribution[].downloadURL[].id'

The first question is, whether downloadURLs should go to the search or the data sub commands.

• dcat data -l id yields a link to the cache, so dcat data -url could yield the link to the appropriate url w.r.t. encoding and format. In fact, the data sub command is concerned with conneg, so the url part fits there best
• dcat search --url could return a simplified json, but it is rather a small quality of life improvement - the jq expression could be simplified to e.g. .[].downloadURL[].
