[Feature Request] filter pokemon based on distance to the current location and their despawn time

[philcerf]

Hey.

This basically builds on the scenario and feature request #154.

When I do shiny hunting (e.g. via bike or car), where I want to click on as many as possible, I Iook at the map to find out an optimised path.

Showing the countdown times on the map would already help a lot.

But even nicer would be if one could apply an additional filter: Hide every pokemon further away than n metres from the current position and having a despawn time of less than t seconds.

That way I could quickly filter out all the ones further away that I wouldn't reach in time, but still the those, which are further away but which I could reach.

Best wishes.
