createImmutableStateInvariantMiddleware not actually exported

[exogen]

Hello! 👋

The Other Exports docs say that createImmutableStateInvariantMiddleware is exported, but it doesn't seem to actually be there: https://github.com/reduxjs/redux-toolkit/blob/master/src/index.ts

Good catch! Can you file a PR to export things from that file?

Also, out of curiosity, do you have a specific use case for needing to call it directly, or is this just observing a bug?

[exogen]

Done!

My app currently uses most of the pieces of the toolkit piecemeal instead of the higher level helpers (it uses redux-dynamic-modules for instance, so we have our own store creation). But in this particular case I may be able to use getDefaultMiddleware, assuming it doesn't matter whether other middleware comes before the immutable state invariant one (I do have some that needs to come before thunk).

[markerikson]

Yeah, ideally the immutable and serializable check middleware come last in the sequence so they can catch things downstream of thunks and such anyway.
