For some reason the vite-plugin-comlink doesn't seem to work in this
constellation.
I tried to reproduce in a new vite project and there it did work.
But also, the plugin does some horrible magic by replacing a
non-existant constructor `ComLinkWorker()` with the `wrap()` method
and then the only real benefit is, that we wouldn't need to write the
`expose()` method in the worker. So for that reason I'm removing the
plugin and using the comlink package directly.
