code: public static <W extends WitnessType<W>,A> OptionalT<W,A> fromAnyM(final AnyM<W,A> anyM) {
          return of(anyM.map(Optional::ofNullable));
      }
docs: Construct an OptionalWT from an AnyM that contains a monad type that contains type other than Optional
  The values in the underlying monad will be mapped to Optional<A>
  
  @param anyM AnyM that doesn't contain a monad wrapping an Optional
  @return OptionalWT
