[BUG] useSIWE() hook return union-typed as any

[volkyeth]

The useSIWE() hook return is union-typed as any: https://github.com/family/connectkit/blob/825f95e8f6bd9fae16803a63efaa14b87137a793/packages/connectkit/src/siwe/useSIWE.ts#L28

That kills all type inference when using it

Running into the same issue, tying is completely bricked for useSIWE() hook.

@ian-os changing the return types breaks a few other places. I have a fix for those as well in #317
