Adjust center of the map based on the user

[archived-m]

Right now, the center of the map on page load is always a hardcoded latitude and longitude, the center of Belgium.

I propose we do the following:

• If a user has a garden, set its location as the map's center
• We can make a geolocation request using user IP (https://geolocation-db.com/json/) to get someone's approximate location
• If the request fails or is blocked and the user is logged in, we can default to the country they provide on registration
• We can ask for the user's location, but I'd find that annoying. I'd default to Belgium if all else fails.

This makes it so that we can increase the zoom level a little, since right now you see a lot you probably don't want to when you first load the page.

This is also the only missing (technical) thing that is preventing widespread use outside of Belgium.

We ask for the user's location if they give us permission, we center the map otherwise it defaults to Belgium.
