Extension of SDK Migration

Following the successful completion of the initial migration phase from SDK6 to SDK7, we propose extending the project for an additional 6 months. The Team, which were previously funded by the Decentraland DAO, have successfully delivered key scene migrations while provided support to content creators. However, there are still many scenes that need to be migrated. During our first stage we recieved a lot of request from scene owners to migrate their scenes and we still have a lot of work to do.
