Clusters not rendering/updating during flyTo or other map animations / dragging

[MarkLyck]

Describe the bug
Clusters do not render, split or update during map animations or while dragging the map from an area with no clusters to an area with clusters.

To Reproduce
Steps to reproduce the behavior:

1. Add a bunch of data points to render clusters, subclusters and markers
2. set viewportChangeMethod="flyTo"
3. drag the map from an area with no clusters to an area with clusters.
4. See that the new clusters don't appear until you let go of the mouse.

Expected behavior
I would expect clusters to update and render during each tick of an animation whether it is dragging the map to an area where a cluster should be rendered, or zooming into a cluster where it should "split" into multiple clusters or markers during the zoom animation.

Screenshots

Additional context
I am attempting to migrate from https://github.com/alex3165/react-mapbox-gl to react-map-gl

The cluster feature of react-mapbox-gl is able to render and split the clusters in real-time during map animations. Not sure if it's worth looking at how they render the clusters?

This is a dealbreaker to finish migrating over.
