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

[volkyeth]

The useSIWE() hook return is union-typed as any:

connectkit/packages/connectkit/src/siwe/useSIWE.ts

Line 28 in 825f95e

| any => {

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
