Implement BookkeptQty and its supertraits

By default, dropping when nonzero is forbidden, and you must have a field bomb: DropBombCondition. #[deftly(allow_nonzero_drop)] suppresses this.

This is a derive_deftly template. Do not invoke it directly. To use it, write: #[derive(Deftly)] #[derive_deftly(BookkeptQty)].
