/**
* Upload the tft file and soft reset Nextion
* @brief Uploads the TFT file to the Nextion display.
*
* This function initiates the upload of a TFT file to the Nextion display. Users can specify a target baud rate for
* the transfer. If the provided baud rate is not supported by Nextion, the function defaults to using the current
* baud rate set for the display. If no baud rate is specified (or if 0 is passed), the current baud rate is used.
*
* Supported baud rates are: 2400, 4800, 9600, 19200, 31250, 38400, 57600, 115200, 230400, 250000, 256000, 512000
* and 921600. Selecting a baud rate supported by both the Nextion display and the host hardware is essential for
* ensuring a successful upload process.
*
* @param baud_rate The desired baud rate for the TFT file transfer, specified as an unsigned 32-bit integer.
* If the specified baud rate is not supported, or if 0 is passed, the function will use the current baud rate.
* The default value is 0, which implies using the current baud rate.
* @param exit_reparse If true, the function exits reparse mode before uploading the TFT file. This parameter
* defaults to true, ensuring that the display is ready to receive and apply the new TFT file without needing
* to manually reset or reconfigure. Exiting reparse mode is recommended for most upload scenarios to ensure
* the display properly processes the uploaded file command.
* @return bool True: Transfer completed successfuly, False: Transfer failed.
