* finalizing: switch to file-management scriptrunner

    Switch to scriptrunner for file management (to lessen user error from incorrectly copying files).
        Thus, users will need to copy just two files: finalize_helper.firm to SD:/luma/payloads/ (which will have to be created by the user) and finalize.romfs (which ends up on root of SD).
        This change allows for better checking of file integrity and lessens the chance of user error from incorrectly copying files.
        The scriptrunner's task is to load finalize.romfs from the SD card, unpack it, and to copy its contents to root of SD.
        The intended location of finalize.romfs is root of SD, but the scriptrunner will attempt to move the file if it is found in SD:/Nintendo 3DS, SD:/DCIM, SD:/luma, or SD:/luma/payloads.
    Remove errors relating to missing files (since that should no longer be possible).
    Add visuals on the top screen for error resolution, with QR codes to the guide / NH where appropriate.
