fix devtools and type middleware properly

[dai-shi]

Close #77

• devtools follows v3 api (replace flag)
• devtools works without name (defaults to action)
• type devtools and redux middleware (a bit messy, can improve?)

Here's how you could use devtools in TS.

const useStore = create<{
  count: number
  increment: () => void
  decrement: () => void
}>(devtools((set, get) => ({
  count: 0,
  increment: () => set({ count: get().count + 1 }, false, "inc"),
  decrement: () => set({ count: get().count - 1 }, false, "dec"),
})));

Here's redux middleware in TS.

const initialState = {                                                          
  grumpiness: 0,                                                                
}                                                                             
                                                                              
const reducer = (  
  state: typeof initialState,  
  action: { type: "INCREASE" | "DECREASE", by: number }                
) => {                                                                          
  switch (action.type) {                                                        
    case "INCREASE": return { grumpiness: state.grumpiness + action.by }        
    case "DECREASE": return { grumpiness: state.grumpiness - action.by }        
    default: return state                                                       
  }                                                                             
}                                                                               
                                                                                
const useReduxStore = create(devtools(redux(reducer, initialState)))
