Export simple type annotations for function-as-a-child arguments

Is your feature request related to a problem? Please describe. Sometimes it is necessary to pass down methods such as refetch and mutate that come from the function-as-a-child arguments of the Get and Mutate components, e.g. child component or a component method at which point they need a type annotation. Currently, this is quite hard to reproduce with the mutate API looking something like this: https://github.com/contiamo/restful-react/blob/master/src/Mutate.tsx#L119.

Describe the solution you’d like The library should export interfaces for these methods taking the number and configuration of generics as the Get or Mutate components themselves. This would make type annotations straightforward and easy to follow.

Oh wow they’re actually the same, never mind I didn’t say anything 😃

The mutate argument in the render props pattern can have the following signatures:

mutate: (body?: string | {}) => Promise<TData>

mutate: (resourceId?: string | {}) => Promise<TData>

and this is based on whether we are working with MutateWithDeleteProps and MutateWithOtherVerbProps, but we won’t be able to tell statically which one. Therefor my suggestion was to export both annotations and leave it up to the user to use the one that’s relevant to each use-case when this comes up.
