[FEATURE] Add dictionary-like prompting for backwards compatibility with PyInquirer

[TheItsNameless]

Feature description
ItsPrompt tries to be a project which is easy to use. A way to make it even easier would be by implementing a backwards compatibility with PyInquirer, as this project is no longer updated since a few years and does not work on the latest python versions.
