proposal: more strict useState types

[Shinyaigeek]

Motivation

In React, [state, setState]`s type returned by useState hooks is inferred with useState's argument or type Parameter.

const [value, setValue] = useState(0);
// value is infered as number, and setValue is infered as (value: number) => void

const [value, setValue] = useState<string>(0);
// type error happens

but in nano,
[state, setState]'s value is inferred as any.

IMO, more strict type will lead better developer experience, so I propose that more strict useState's type.

If this feature is needed, can I work on this?
