v2.1.0

Added combine function to help with type inference

The new combine function combines initial state and actions together to help
with TypeScript type inference.

const useCount = create(
    combine({ count: 0 }, (set) => ({ 
        inc: set(state => ({ count: state.count + 1 }) 
    }))
)
