A Riduce-standard action, produced by Riduce's actions and create API.

It builds off Flux-Standard Actions, but adds a leaf property, which is used by Riduce's reducer to identify which state to update and how.

interface Action<PayloadT = unknown> {
  type: string;
  leaf: LeafData;
  payload?: PayloadT;
}

The presence of the leaf property has two handy properties:

1. Using type exclusively for debugging: since leaf contains the data needed for Riduce's reducer to update state, the type property can be used exclusively for debugging and readability - see Control action types
2. Easy migration from legacy reducers: since leaf is guaranteed to be present on all Riduce actions, it can be used to help gradually migrate from legacy reducers - see Migrating from legacy reducers
