Support for input forms

[ZenoArrow]

Is your feature request related to a problem? Please describe.
I'd like to build forms that would allow data to be edited.

Describe the solution you'd like
The ability to create forms that allow data to be entered and edited. Ideally it would be good to be able to tab between fields in these forms.

Describe alternatives you've considered
Other TUI libraries support this feature, and I've considered using them, but I'd like to be able to do this within Spectre.Console.

Additional context
Here's an example of the type of form I'd ideally like to be able to create, it doesn't have to appear in a pop-up dialog as shown in this screenshot, but the general layout and functionality reflects what I'm looking to achieve in Spectre.Console:

Thank you for posting an issue, but this goes beyond the scope of what Spectre.Console is, so this is not something that we will consider. I would recommend you to take a look at something like Textual or GUI.cs
