Title: Added parsing of map gateway and hash. 

With the gateway and hash of the map, you can access the actual map file via the following url template:

http://{gateway}.depot.battle.net:1119/{lowercase-hex-encoded-hash}.s2ma

For example, Metalopolis can be found at http://us.depot.battle.net:1119/cadd112e2aca3ed743863b669bb869ce86cdce3ad6171087b8182abe4ac8e9cd.s2ma

This information allows users of the replay parser to download the map file associated with the replay, to do things like e.g. display a minimap image.
