Add support for realm param #42
Description
Add support for the realm param. E.g: https://decentraland.org/jump/?realm=https://sdk-team-cdn.decentraland.org/ipfs/goerli-plaza-main-latest&position=74,-2 ). It should load a scene in the goerli-plaza realm but it's actually loading those coords in Genesis City, ignoring the realm param.
The deeplink works: decentraland://?realm=https://sdk-team-cdn.decentraland.org/ipfs/goerli-plaza-main-latest&position=74,-2
