Custom Error Types Using Cats Effect and MTL

One of the most famous and longstanding limitations of the Cats Effect IO type (and the Cats generic typeclasses) is the fact that the only available error channel is Throwable. This stands in contrast to bifunctor or polyfunctor techniques, which add a typed error channel within the monad itself. You can see this easily in type signatures: IO[String] indicates an IO which returns a String or may produce a Throwable error ( Future[String] is directly analogous).
