Module animation 

Animation subsystem for the matrix_gui framework.

This module provides a lightweight animation system inspired by LVGL 8, designed for immediate-mode embedded GUI applications.

Features

• Multiple easing functions using integer-only math (no floating point)
• Support for value animations with callbacks
• Animation management with play, pause, stop controls
• Memory-efficient design suitable for embedded systems
• no_std compatible

Core Components

• Anim: Animation definition with start/end values, duration, and easing
• Easing: Easing functions for smooth animations (integer-based)
• AnimManager: Manages multiple active animations
• [AnimCallback]: Callback trait for animation value updates
