[ios] Sort candidate annotations by proximity to tap

If you tap near a tight cluster of annotations, the annotation directly beneath your finger should be selected first. Previously, the annotations within the query bounds would be selected in order from oldest to newest, which was counterintuitive. The new behavior does sometimes make it more difficult to cycle through the entire cluster, but the previous behavior often got in the way anyways, as your finger would wind up atop a callout view for an annotation farther south.

Also updated the changelog.

 ## iOS master
 
 - `MGLMapView` methods that alter the viewport now accept optional completion handlers. ([#3090](https://github.com/mapbox/mapbox-gl-native/pull/3090))
+- Tapping now selects annotations more reliably. Tapping near the top of a large annotation image now selects that annotation. An annotation image’s alignment insets influence how far away the user can tap and still select the annotation. For example, if your annotation image has a large shadow, you can keep that shadow from being tappable by excluding it from the image’s alignment rect. ([#3261](https://github.com/mapbox/mapbox-gl-native/pull/3261))
+- The user dot’s callout view is now centered above the user dot. It was previously offset slightly to the left. ([#3261](https://github.com/mapbox/mapbox-gl-native/pull/3261))
