Support current version of Django and Django Channels

[brot]

Django Channels only supports Django up to 4.0. For newer Django versions there is Django Channels 4.x which supports already Django 4.1 and 4.2, but it's a major version change which a lot of deprecations and removals, so django-eventstream does not work with a current version of Django and Django Channels

Indeed. There is some discussion about this in #100.
