Generic LCD driver as a ESP32 Component

=======================================

This is a generic LCD driver wrapped as a ESP32 component. You are free to use

the driver component as you wish as long as you follow the license agreement in

[LICENSE.md](LICENSE.md).

Usage Example

-------------

```c

int lcdBusIO(lcdDriver_t *driver, bool rw, bool rs, bool en, uint8_t data)

{

    // Implement for your own setup.

}

int lcdDelay(lcdDriver_t *driver, uint32_t delay)

{

    // Implement for your own setup.

    return usleep((useconds_t)delay);

}

void app_main(void)

{

    lcdDriver_t lcd = {

        .userData = NULL,

        .dimensions = {16, 2},

        .writeOnly = true,

        .fourBits = true

    };

    // Do GPIO initialization.

    // Reset GPIO pins to their default state.

    lcdBusIO(&lcd, false, false, false, 0xFF);

    lcdLoadDefaultTiming(&lcd);     // Load default LCD timings.

    lcdInit(&lcd);                  // Initialize the LCD and driver.

    lcdDirection(&lcd, true);                   // Set the direction to forward.

    lcdSetDisplay(&lcd, true, false, false);    // Enable display.

    lcdHome(&lcd);                              // Home the LCD cursor.

    lcdPutZString(&driver, "Hello World!");

}

```

TO-DO
