This upgrades the OpenLayers library to the latest 9.1.0 version. According to the upgrade notes of OL no further code changes seem to be necessary in the Wegue code.
But be aware that your custom application code maybe needs some adaption due to the breaking changes in OpenLayers 9.0.0. Check the link above for details.
Thanks for your review @sronveaux. Since it has been a couple of weeks I also did another test with a bigger Wegue app. Works as expected, so I am going to merge now.
