I am going to merge this since the PR doesn't change anything in the way existing RGB20 assets behaved; it just shifts from the outdated schema rust syntax to interfaces and use of Contractum. If there are questions related to the RGB20 business logic defined by the standard they should be proposed with a PR after a discussion in https://github.com/LNP-BP/LNPBPs/discussions/140
