Make coordinates clickable everywhere

[argilo]

In a couple places, it's possible to click on coordinates to bring up an external mapping application:

• sidebar (balloon / chase car details)
• landing prediction popup

Elsewhere, coordinates are displayed as plain text. It would be convenient to have coordinates displayed as a clickable link everywhere.

Here I extracted the common code for generating a link into a function (format_coordinates), and used it to display coordinates in the following places:

• historical landing popup
• balloon path popup
• recovery popup
• recoveries pane

Thanks for this! Could you please redirect this PR to the testing branch?

[argilo]

Sure, I'll do that in a few hours when I'm back at the computer.

I forgot to mention that I tested this on desktop and Android, but not with iPhone as I don't have a device to test with.

Rebased and re-tested.

Thanks! This is also cleans up the code a bit which is nice. It would be good to have this on sondehub-amateur-tracker too.
