(WIP) more progress with the brig x d.v4 animation

This is gonna be longer than what i usually make. Like i said last time d.v4 will be fully animated at the end. For now i'm focussing only on brig and some main d.v4 movemets. If everything goes to plan, the end will be special, and yeah actually i'm thinking to make this the 2023 xmas animation.
