fix: correct type problem on rest parameter

[mat813]

The error was:

.../types/index.d.ts:9:29 - error TS2370: A rest parameter must be of an array type.

9 type AsyncFunction<A, O> = (...args: A) => Promise<O>;
                              ~~~~~~~~~~

So enforce the parameter to be some kind of array.
