WaveShare ESP32-S3 LCD 1.69 round corner configuration

[grovedc]

I created a configuration for the aforementioned board. It runs the PDQgraphicstest just fine.

// #define WAVESHARE_ESP32_S3_LCD_1_46
// #define WAVESHARE_ESP32_S3_LCD_1_47
#define WAVESHARE_ESP32_S3_LCD_1_69
// #define WAVESHARE_ESP32_S3_LCD_2_8

#elif defined(WAVESHARE_ESP32_S3_LCD_1_69)
#define GFX_DEV_DEVICE WAVESHARE_ESP32_S3_LCD_1_69
#define GFX_BL 15
Arduino_DataBus *bus = new Arduino_ESP32SPI(4 /* DC */, 5 /* CS */, 6 /* SCK */, 7 /* MOSI */, GFX_NOT_DEFINED /* MISO */);
Arduino_GFX *gfx = new Arduino_ST7789(
    bus, 11 /* RST */, 0 /* rotation */, true /* IPS */, 240 /* width */, 280 /* height */,
    0 /* col offset 1 */, 20 /* row offset 1 */, 0 /* col offset 2 */, 20 /* row offset 2 */);
