RUSTSEC-2020-0029: rgb: Allows viewing and modifying arbitrary structs as bytes

Description

Affected versions of rgb crate allow viewing and modifying data of any type T wrapped in RGB<T> as bytes, and do not correctly constrain RGB<T> and other wrapper structures to the types for which it is safe to do so.

Safety violation possible for a type wrapped in RGB<T> and similar wrapper structures:

The issue was resolved by requiring all types wrapped in structures provided by RGB crate to implement an unsafe marker trait.
