- A `jupyter-org-client` is a subclass of a `jupyter-repl-client` and replaces
the use of callbacks in `org-babel-execute:jupyter` to handle the insertion
of code block results in an `org-mode` buffer. `ob-jupyter.el` now only
contains the integration with `org-babel` and all integration with
`emcacs-jupyter` is placed in `jupyter-org-client.el`
- Introduce `jupyter-org-request`, which inherits all of the field of a
`jupyter-request` and adds the fields necessary for keeping track of the
source code block information a request was generated from during the
lifetime of the request.
