TT21100 touch driver does not support interrupt based reading

[TTauriainenQt]

TT21100 touch driver does not support interrupt based reading.

https://github.com/espressif/esp-box/blob/cc7610df2d8ddeab334695e748f7ed938940c895/components/i2c_devices/touch_panel/tt21100.c#L176-L184

Suggested functionality:

esp_err_t tt21100_tp_init(void)
{
...
    // Register interrupt for GPIO_NUM_3 falling edge / tt21100_touch_interrupt()
...
}

void tt21100_set_callback(void (*callback)())
{
    // Store callback function
}

void tt21100_touch_interrupt()
{
    // Call the callback function if it is set
}

Good suggestion! Interruption does have higher efficiency, and we will make improvements in the near future.
