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.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced
