Create lootbox manager

Creates a new game lootbox manager and deploys a lootbox manager contract on behalf of the authenticating game's primary wallet. The deployed lootbox manager contract allows you to create lootbox behavior for existing items. For example, you can define item id(s) from one of your item collections as the requirement(s) to open a "lootbox". The required item(s) would be burned from the interacting player's wallet and the player would receive item(s) from a weighted randomized set of possible items the lootbox can contain.
