ESP32FTPServer

Simple FTP Server for Espressif ESP32 Based on the work from https://github.com/HenrikSte/ESP32FTPServer and https://github.com/MollySophia/ESP32_FTPServer_SD (which again is based on https://github.com/robo8080/ESP32_FTPServer_SD)

Just resized the global buffer and introduced method isConnected().
SD_MMC is now supported (thanks to tueddy for the contribution).
Be advised that only one simultaneous connection is possible. I recommend Filezilla as it's a multi-OS-platform and this parameter can be configured there.

}

void loop(void){
    ftpSrv.handleFTP();        //make sure in loop you call handleFTP()!!
}

// optional

    Serial.printf("ftpdebug: %s  \n", debug);
