Module rendering 

Rendering module for terminal-based output.

This module provides the core rendering components for the teng library, enabling you to display graphics and text in a terminal environment.

Sub-modules:

• color: Defines the Color enum for specifying colors.
• display: Defines the Display struct, a 2D pixel buffer.
• pixel: Defines the Pixel struct, the basic unit of rendering.
• render: Provides the Render trait for objects that can be rendered.
• renderer: Defines the Renderer trait and implementations for rendering to the terminal.

Key Concepts:

• Pixels: The fundamental unit of rendering, represented by the Pixel struct. Pixels define a character and its foreground and background colors.
• Display Buffer: The Display struct is a 2D grid of pixels that acts as an in-memory representation of the terminal display.
• Renderer: The Renderer trait defines the interface for rendering operations. DisplayRenderer is a concrete implementation that renders to the terminal using crossterm.
• Renderable Objects: Anything that implements the Render trait can be drawn to the display using a Renderer. This includes strings, characters, pixels, and sprites.

Rendering Process (Simplified):

1. Create a DisplayRenderer (which manages the terminal output).
2. Get a mutable reference to the Renderer within your Component::render() method.
3. Use methods like Renderer::render_pixel() and Render::render() to draw pixels and renderable objects to the Renderer.
4. The Renderer updates its internal Display buffer.
5. Call Renderer::flush() to write the contents of the Display buffer to the terminal, efficiently updating only the changed pixels.
