support for Realtime table

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

• The feature I want to propose would be useful for the majority of users, not only for me personally.
• 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.
Some busstations have huge delays. It would be nice If I could see the delays.

Describe the solution you'd like
If delay information is available show it alreay on the list of connection. If delays not work with the switch of transports prompt a warning or remove it from the list.

Which network are you using? Delay information can already provided by some networks API.

As for GTFS-RT, I will quote @ialokim: #748 (comment)

We rely on PTE as our data source and unfortunately this library does not support GTFS realtime APIs. It even does not handle static GTFS files directly, but relies on Navitia for providing a clean API.

Supporting GTFS and/or GTFS-RT is interesting but would require major changes.

I us Transportr 1.1.9 from fdroid. it's strange but i do not find it anymore on fdroid.
i use an other app since a while because delay not worked. And last time i tested also sbb and zvv not work.
As far i know there should be an update to an other provider than sbb in one of the next release.

This is a very outdated version, see why here #826. For SBB a fix should be available in the next release (that should be back in F-Droid).
The current version 2.1.5 works fine for ZVV, so feel free to try it out (PlayStore or APK from GitHub https://github.com/grote/Transportr/releases/tag/2.1.5).

[Mannshoch]

Oh... 😅 ... Sorry for that.
I do not have PlayStore installed. I will wait.

Transportr is available via F-Droid again from version 2.2.0. ZVV and SBB should work fine there.
