Add option to generate props for cloudinary-react

For example: can add a cldFixed, cldFluid, cldSomeTransformation objects, like the fluid/fixed objects that are added for easy integration with gatsby-image.

It could then be used like this:

import {Image} from 'cloudinary-react';
/* get cldTransformations using GraphQL*/

in render():



etc...

Start by tracing the existing fluid/fixed objects generated for Gatsby image integration and how GraphQL results are exposed to cloudinary-react. Clarify the intended generated prop shapes and transformation variants, then verify that the proposed objects can be spread into the shown Image examples.
