feat: Add Metro Station Map

[kazimmt]

You can add a different tab or menu to show the stations map
So people can find the stations easily

Something like this: https://www.google.com/maps/d/viewer?mid=1snBTSj_LQEpBhzfcMTaCD-huo6m63aw

@aniruddha-adhikary need to change our layout, bottom nav, or fragment approach!

@aniruddha-adhikary dada, I have an idea for it. In this case, we can use open street map (OSM), which will work on both platforms. It is completely free and doesn't require any API keys to use.

I can contribute here if anyone is not working on this.
