Rotation based on heading going opposite of Google / Apple (iOS)

[parrots]

When setting the direction in MapBox GL to a specific heading it seems to rotate in a direction opposite Google Maps and Apple. Meaning at 0 and 180 the maps line up but at 90 MapBox is at an Apple equivalent to 270.

Probably just need to reverse the direction you start to rotate based on a heading.

As @friedbunny points out, we’re also inconsistent with mapbox/mapbox-gl-js. From the documentation for -[MKCamera heading]:

The value 0 means that the top edge of the map view corresponds to true north. The value 90 means the top of the map is pointing due east. The value 180 means the top of the map points due south, and so on.
