Inconsistency with registry.storage<const Component> and storage_for_type<const Component>

[n0F4x]

registry.storage<const Component> would give back a const Storage&, but the function runs into a static_assert, which says that only non-const Components are allowed (e.g. registry.storage<Component>, this gives back a non-const Storage&)

Either const Components should be allowed, or there is no use for substituting the return type into a const Storage&.

This is annoying when one uses the registry's storage_for_type<Component> to figure out what Storage a Component would have.
