Feature Request: filter_map for GraphMap

[bramp]

Summary

Add the filter_map function to the GraphMap type

Motivation

filter_map is a simple way to filter nodes and edges from Graph and StableGraph, but seems missing from GraphMap.

Details

• What code needs to change? New traits? Which modules?

Sorry I'm not sure.

Ok I created a solution here #703

@mark-addams001881 thanks for your solution. It wasn't quite right, so I didn't use it.
