No SD card window

[DrNorfolk]

I noticed that the vga-window does not work, which should display a warning that the sd card is missing. There is code in the FileUtils.cpp file that I think should do this, but nothing appears on the screen.

    if (!SD.begin(SDCARD_CS, customSPI, 4000000, "/sd")) {
        Serial.println("Card Mount Failed");
        OSD::errorHalt(ERR_FS_EXT_FAIL);
        return;
    }

OSD::errorHalt(ERR_FS_EXT_FAIL);

The following is output to the console:

Rebooting...

And then the esp32 goes into reboot indefinitely, until you insert the SD card. It would be very nice if the window "Sir Clive is smoking in the Rolls... Cannot mount external storage!" on the screen. Thank you dcrespo3d for your work!

As an alternative, if the SD card is missing, theoretically you can "fall back" to OpenSE Basic: https://spectrumcomputing.co.uk/index.php?cat=96&id=27510 (GPL v2.0) instead of just failing.
