a11y support

Problem

Interactive tui apps usually dont have concise accessibility feature support, and sometimes they might be hard to use.

Solution

Add feature to enable support for accessibility features. Could be done using AccessKit. There are maybe other frameworks for it, but this is open to suggestion

Are you willing to contribute an implementation?

• I am willing to open a PR implementing this.
• I can try to implement it, but I will need guidance.
• I am not able to implement this right now.

Additional context

This might be also used for some autotests via things like xa11y
