/**
* Sets Nextion Protocol Reparse mode between active or passive
* @param True or false.
* active_mode=true to enter active protocol reparse mode
* active_mode=false to enter passive protocol reparse mode.
* @brief Sets the Nextion display's protocol reparse mode.
*
* This function toggles the Nextion display's protocol reparse mode between active and passive.
* In active mode, the display actively parses incoming data.
* In passive mode, it does not parse data unless specifically instructed to do so.
* This is useful for managing how the Nextion display interprets incoming commands,
* especially during initialization or in scenarios where precise control over command processing is needed.
*
* @param active_mode A boolean value indicating the desired reparse mode.
* - true to set the display to active protocol reparse mode, where it actively parses incoming commands.
* - false to set the display to passive protocol reparse mode, where command parsing is done only on explicit
* instruction.
*
* @return bool Returns true if all commands were sent successfully to the Nextion display, indicating that the mode
* was set as expected. Returns false if any of the commands failed to send, indicating that the desired reparse mode
* may not be correctly set.
