feat: Visualize MapAction action in transparency

## Issue
I'm creating a burr graph out of a yaml config, with potential recursive map_action inside.
It might become a bit complex and I would like to visualize the full graph in transparency instead of the MapAction subgraphs being wrapped inside a single node.

## Solution I'd like
An option to display a MapAction node in transparency (displaying all the subgraphs inside it).

## Considered Alternatives
I'm going through an intermediate process using networkx while parsing my yaml file. So I visualize first using networkx. But I may miss some mistakes in my config that would become clear and obvious once I display the full burr graph.

Start by locating the transparency visualization entry point and how recursive MapAction nodes are represented when loading the YAML graph. Define done as an option that expands MapAction subgraphs in the full graph while preserving the existing collapsed view, and verify it with a recursive MapAction configuration.
