Add support for image_and_json format

[SolomonLake]

Description

Adds new format option for v0 http request, image_and_json. This will create the image visualization, and return it with the predictions json. Also updates inference_sdk to output the image in the desired format (pillow, numpy, etc).

Adding this as a separate initiative to the ongoing workflows feature improvements because it is relatively small update.

I need to deploy to the hosted api for testing. I'll coordinate with you to do this ASAP.
