More control over serializableCheck option in middleware?
I'm using redux-toolkit with redux-persist. In order to avoid serialization errors, middleware is configured to ignore redux-persist actions:

```
 serializableCheck: {
 		ignoredActions: [FLUSH, REHYDRATE, PAUSE, PERSIST, PURGE, REGISTER]
},
```

I don't see a point of checking if actions are serializable if I am not using time-travel or other features. If action has a payload that is not serializable, it doesn't mean I am going to put that data as-is in the store. For example, my app works with dates and I would like to use dates in actions and store them in the state as strings. Or I might be using Set or Map to send data in action, but reducer will store that data as serializable data in the store.

Is there any option to skip checking **only for actions**? All of them? But leave this checking for the state.

I expected something like this, but this is not working:

```
 serializableCheck: {
 		ignoredActions: ['*']
},
```
