It might be interessing to support "limit" and "offset" parameters in QIDO-RS requests, especially to shorten the response time when listing instances for example.

A few example:
http://127.0.0.1:8042/dicom-web/studies?limit=20
http://127.0.0.1:8042/dicom-web//studies/{StudyInstanceUID}/series?limit=10
http://127.0.0.1:8042/dicom-web//series?limit=50

Using limit and offset to get the json info for only one instance in the middle of the image stack:
http://127.0.0.1:8042/dicom-web//studies/{StudyInstanceUID}/series/{SeriesInstanceUID}/instances?limit=1&offset=100

This is solved by the combination of the two following changesets (the version of the core of Orthanc must be >= 1.2.1):
