More for left handed

Currently in bedrock you can only hold 6 items in the offhand (if i remember right) being shield, totem, map, arrows, rockets and nautica shell. And you can't even use the rockets, only with a crossbow. I don't mind not being able to hold tools with offhand, but torches and food would make the BE alot better. Also make the player be able to use the offhand rockets while cliding with elytra.
