Improve the homepage map to reflect geolocations of all images

[kevinsbarnard]

Right now the map doesn't entirely represent where all the images in FathomNet are located. Suggestion: render the map based on all images instead of one point per collection.

Tthe code that generates the map image is currently run under my account in a cronjob on quasar.
