title: How to get the current CRS of a networkx.MultiDiGraph when using OSMnx?
body: <p>I obtained an <code>osmnx.graph_from_bbox</code> and cannot find a function to get the current projection (<strong>CRS</strong>). My purpose is to check the CRS of a graph somewhere in my code and decide if it needs to be projected (<code>osmnx.project_graph</code>) or leave it as it is. I appreciate your help!</p>
