Investigate use of textualise for TUI CDDS applications

Migrated Jira Issue CDDSO-260
Jira creation date 30/03/2023 20:32
-------
Textualize is a python library for creating TUI applications. See [https://www.textualize.io/|https://www.textualize.io/|smart-link]

At present we are using ``rose edit`` almost like a pseudo GUI for an alternative way to create ``request.json`` files. Using textualize could give us an alternative way for users to interface with CDDS and give us greater flexibility over how things are presented to the user.
-------

Start by reviewing the current `rose edit` workflow and how it creates `request.json` files. Read the Textualize documentation and compare its suitability for a CDDS TUI; done means documenting the findings and defining whether an alternative interface should be pursued.
