Compose stage detection is broken

Q	A
BC Break	no
Version	0.5.0

In https://github.com/veewee/reflecta/releases/tag/0.5.0, the templates on Lens and ISO were marked as covariant.
This breaks the psalm plugin that detects the parameter types in compose() for both lenses and isos.

Expected:

/**
 * @template A
 * @template B
 * @template C
 * @template D
 *
 * @param Lens<A,B> $lens1
 * @param Lens<C,C> $lens2
 * @param Lens<C,D> $lens3
 * @return Lens<A,D>
 *
 * @psalm-suppress InvalidArgument
 */
function it_knows_broken_composition(Lens $lens1, Lens $lens2, Lens $lens3): Lens
{
    return compose($lens1, $lens2, $lens3);
}

Yet, the InvalidArgument does not get triggered anymore. It is possibly not implemented in the dynamic function storage system.
To investigate and reactivate in the SA tests!
