[Feat] Add getmaxWidth to Text Layer

[pentamorfico]

Target Use Case

I'm currently using a PolygonLayer, and showing some text under the polygons. I would like to use a maxWidth independent for each element. so that the maximum width of each text object is constrained by the associated polygon size.

Is there any way to implement a data accesor for the maxWidth parameter?

Proposal

The idea is just to add the possibility to create a Data Accessor for maxWidth
