Modify populartimes_get() to accept a single lat/lon location and search radius

[gabriel-happle]

I would like to have the option to define individual search coordinates and search radii. For the case where I am able to define my own lat/lon lattice/grid, e.g., based on a polygon shape, the populartimes_get() function could either accept single search coordinates and a radius or a list of search coordinates and corresponding radii.

Hey @gabriel-happle - were you able to perform this ever? I see a radius parameter, but it doesn't function as you've described for some reason.
