Swapped out map tile provider

Screenshot of the map with the new tiles, also showing my GPS track across the southern Balkans.

Switched map tiles provider from Thunder Forest Outdoors to maptiler.

Much prefer the topographic styling of these maps. They even offer a set of satellite tiles if I decide I want that option in the future.

Before and after:

  .then(() => {
    var map = L.map('map');
    L.tileLayer('https://tile.thunderforest.com/outdoors/{z}/{x}/{y}.png?apikey=APIKEY', {
        maxZoom: 19,
        attribution: null
    }).addTo(map);

  .then(() => {
    var map = L.map('map');
    L.tileLayer('https://api.maptiler.com/maps/topo-v2/{z}/{x}/{y}.png?key=APIKEY', {
        maxZoom: 19,
        attribution: null
    }).addTo(map);
