    epsonds: Give names to group options
    
    The group options currently do not have names set.  Since only the title
    is supposed to be valid for group options, this isn't a violation of
    the SANE standard.  Regardless, it causes scanimage (and maybe other
    frontends) to skip them.  Add empty name values so that they can be
    processed properly.
    
    Before:
    Options specific to device `epsonds:net:n.n.n.n':
      Standard:
        --source Flatbed|ADF Front|ADF Duplex [Flatbed]
            Selects the scan source (such as a document-feeder).
        --mode Lineart|Gray|Color [Color]
            Selects the scan mode (e.g., lineart, monochrome, or color).
        --depth 1|8bit [8]
            Number of bits per sample, typical values are 1 for "line-art" and 8
            for multibit scans.
        --resolution 75|150|300|600|1200dpi [75]
            Sets the resolution of the scanned image.
        -l 0..215.9mm [0]
            Top-left x position of scan area.
        -t 0..297.18mm [0]
            Top-left y position of scan area.
        -x 0..215.9mm [215.9]
            Width of scan-area.
        -y 0..297.18mm [297.18]
            Height of scan-area.
        --eject [inactive]
            Eject the sheet in the ADF
        --load [inactive]
            Load a sheet in the ADF
        --adf-skew[=(yes|no)] [inactive]
            Enables ADF skew correction
        --adf-crp[=(yes|no)] [inactive]
            Enables ADF auto cropping
    
    After:
    Options specific to device `epsonds:net:n.n.n.n':
      Standard:
        --source Flatbed|ADF Front|ADF Duplex [Flatbed]
            Selects the scan source (such as a document-feeder).
        --mode Lineart|Gray|Color [Color]
            Selects the scan mode (e.g., lineart, monochrome, or color).
        --depth 1|8bit [8]
            Number of bits per sample, typical values are 1 for "line-art" and 8
            for multibit scans.
        --resolution 75|150|300|600|1200dpi [75]
            Sets the resolution of the scanned image.
      Geometry:
        -l 0..215.9mm [0]
            Top-left x position of scan area.
        -t 0..297.18mm [0]
            Top-left y position of scan area.
        -x 0..215.9mm [215.9]
            Width of scan-area.
        -y 0..297.18mm [297.18]
            Height of scan-area.
      Optional equipment:
        --eject [inactive]
            Eject the sheet in the ADF
        --load [inactive]
            Load a sheet in the ADF
        --adf-skew[=(yes|no)] [inactive]
            Enables ADF skew correction
        --adf-crp[=(yes|no)] [inactive]
            Enables ADF auto cropping

    epsonds: Allow querying OPT_ADF_CRP
    
    The OPT_ADF_CRP (adf-crp) option is detectable from the hardware and is
    settable as an option, but can't be queried.  This appears to just be an
    oversight, so add it to the list of handled options.
