LCD 1602 Driver

Basic Usage:

1. Initialize pins:
   • Initialize three push-pull pins for RS / RW / E of LCD1602
   • Initialize 8 or 4 open-drain pins for DB0~DB7 or DB4~DB7 of LCD1602
   • Initialize a delay timer(which implement embedded_hal::blocking::delay)
2. Use 8 pin Pins::new() or 4 pin Pins::new() to create a Pins struct containing all initialized pins
3. Use the Builder::new() to create a Builder struct with Pins and the delay timer
4. Use the functions provided by Builder to configure the initial state of the LCD1602
5. Use the .build_and_init() to convert the Builder to an LCD struct, and initialize the LCD1602
6. Use LCD struct:
   • LCDBasic trait provides functions close to LCD1602 instructions
   • LCDExt trait provides commonly used non-animation functions
   • LCDAnimation trait provides simple animation functions
