(SightViewer): add support for DicomWeb
Description
While SightViewer is now the new main application delivered with Sight, it still lacks some features. For instance, it can connect to a PACS using DIMSE-C, but not through DicomWeb.
Proposal
Add support for dicom web, either in the same modal DICOM window, or in an another one.
Outcomes
This will improve the support of DICOM.
Links / references
To test this, you will need a DICOM server. Orthanc can be easily deployed to test that.
