Add Desktop widget "next departures at a station"

Acknowledgments Please check the following boxes with an x if they apply:

• [x] The feature I want to propose would be useful for the majority of users, not only for me personally.
• [x] I am aware that Transportr is mostly developed by one person in their unpaid spare time.
• [ ] I can help myself to get this feature implemented or know someone who wants to do it.
• [ ] If I want to add support for a new region or country, I checked that this is already available in public-transport-enabler and know the process described on the Transportr homepage.

Is your feature request related to a problem? Please describe. I regularly board a train or bus from the same station and then I use a connection that I already know and don't need to look up. However, sometimes a bus or train is delayed, or the service is interrupted, e.g. because of some accident etc. Then I arrive at the station just to notice that I have to find an alternative for my trip – an information that would have served me much better already on the way or when leaving my home.

Describe the solution you'd like I'd like Transportr to offer Desktop widgets for a certain station that show the next departures, incl. delays or cancelled trains. Basically something this app is already doing, but only for Czechia and Slovakia].

With such a widget, I just need to unlock my Android and already on the Homescreen, I see the next departures (incl. delays) from the station I'm walking to.

Describe alternatives you've considered Öffi does offer such widgets but they are buggy when refreshing, plus you cannot filter for transport types or directions (e.g. at a stop like Berlin-Lichtenberg, I might only want to see S trains to the center, not buses or regional trains).
