[TypeScript]: export types and interfaces for reuse (still missing export in 3.0.0)

[NotEvenANeko]

What's on your mind?

For example, I want to make a React hook like

export const useOneSignal = (options?: Parameters<(typeof OneSignal)['init']['0']>): [ready: boolean, instance: typeof OneSignal]

and I have to use Parameters<(typeof OneSignal)['init']['0']> instead of IInitObject.

Export IInitObject and other types can make this function signature easier to write.
