Inline tui as helix-tui fork.

We only rely on some of the rendering primitives and implement our
Cursive-style compositor on top.

+//! `widgets` is a collection of types that implement [`Widget`] or [`StatefulWidget`] or both.
+//!
+//! All widgets are implemented using the builder pattern and are consumable objects. They are not
+//! meant to be stored but used as *commands* to draw common figures in the UI.
+//!
+//! The available widgets are:
+//! - [`Block`]
+//! - [`Tabs`]
+//! - [`List`]
+//! - [`Table`]
+//! - [`Paragraph`]
+//! - [`Clear`]
