Usage

$featureCollection = (new FeatureCollection)->setBbox([0, 0, 1024, 1024]);

// add a single feature
$feature = new Feature([512, 512], 'Point', 1);
$featureCollection->addFeature($feature);

// add an iterable of features
$featureCollection->addFeatures([$feature, /* ... more features ... */]);

// create the GeoJSON, feed leaflet
$json = $featureCollection->toJSON();
{
    "type":"FeatureCollection",
    "bbox":[0, 0, 1024, 1024],
    "features":[
        {
            "type":"Feature",
            "geometry":{
