Description

store.set() should support the functional form, as per https://reactjs.org/docs/hooks-reference.html#functional-updates, in order update the state based on an instruction, instead of the current value (which may be out of date in an async scenario).

Contributor guide

Research direction
Examine undux's store.set() implementation and React's functional update pattern to implement similar behavior for asynchronous updates.
