@brief Register UART interrupt handler (ISR).
@note UART ISR handler will be attached to the same CPU core that this function is running on.
@param uart_num UART_NUM_0, UART_NUM_1 or UART_NUM_2 @param fn Interrupt handler function. @param arg parameter for handler function @param intr_alloc_flags Flags used to allocate the interrupt. One or multiple (ORred) ESP_INTR_FLAG_* values. See esp_intr_alloc.h for more info. @param handle Pointer to return handle. If non-NULL, a handle for the interrupt will be returned here.
@return - ESP_OK Success - ESP_FAIL Parameter error
