Add map los angeles (with roads) (#3708)

## Description:

Add Map - Los Angeles (With Roads)
Whats NY without LA? What is LA without its roads? Here is a larger map
where I have turned LAs road network into rivers. Nations named to areas
of the city or surrounding area. Map geo data is from OpenTopography. I
stenciled the highways from screenshots of online maps and some artistic
choice.
