Have IIIF canvas JSON delivered correctly
Canvases are linked within the manifests <https://textgridlab.org/1.0/iiif/manifests/textgrid:30xbs.0/manifest.json> as follows: <https://textgridlab.org/1.0/iiif/manifests/textgrid:30xbs.0/canvas/textgrid:30wvf.0.json> This works for TextGrid objects, but not for DARIAH's, see <https://trep.de.dariah.eu/1.0/iiif/manifests/hdl:21.T11991%2F0000-001B-5184-2/manifest.json>: <https://trep.de.dariah.eu/1.0/iiif/manifests/hdl:21.T11991%2F0000-001B-5184-2/canvas/hdl:21.T11991%2F0000-001B-5185-1.json> (Have we also to check for sequences and annotations??)
