Heatmap: Data Accessor for radiusPixels

[janhartmann]

Target Use case

Currently, the HeatmapLayer supports radiusPixels to define the radius of each point drawn. However, this is fixed to all points drawn. I am in a situation, where I know exactly what the radius for each point should be, so by having a property data accessor (like the getWeight) I would be able to control each point.

Proposed feature

Introduce a getRadiusPixels data accessor and deprecate the radiusPixels property. By default each point will use a radiusInPixels of 30.
