Map: add clustering distance prop

[bgilhome-now]

Describe the feature

Depending on the number/spread of markers in a map, it might be useful/desired to set the clustering distance, or even disable clustering. Adding clusteringDistance as an optional prop to RplMap (with default as current at 100) could achieve this.

Motivation

In the current EPA project, the custom map uses RplMap to render the map & markers. However, there are instances where the client would like to disable clustering.

Proposal

Add clusteringDistance as an optional prop to RplMap and pass to the ol-animated-clusterlayer component in the template. PR will be created for this.

Benefits

More control over clustering.

Drawbacks

Possibility of developers setting non-sensible clustering distance values.

Adoption strategy

Update documentation - on breaking changes.
