Proper MediaFragments parsing ?
In IIIF, annotations are w3c webannotations which use Fragment Selectors, and in our case, for video, Media Fragments (and IIIF extensions) for eg selecting at which time of a video an annotation should be displayed. Media Fragments allows temporals selectors like t=,20
; which doesn't seems to be handled in the actual code (here and here) for example).
We should fix this if we wants more compatibilty, and particularly if there is a library to do this
