A reader for Yokagawa CellVoyager datasets - WIP

Yokagawa CellVoyager microscope can acquire large areas composed of
several tiles. Each plane (1C, 1Z, 1T) is stores as one plain tiff file
per tile.

Apparently:

- The stitching is done border to border. There are no
subtleties in arranging the tile in space. Mistakes can be seen even in
the proprietary software. Maybe some registration is done prior to
saving; we could not assess for sure.
- The CellVoyager is a spinning-disk. Individual tiles are corrected for
uneven illumination, apparently using a circular gaussian, prior to
saving. This can be seen on densely labeled tiles by changing the display
min&max.

The metadata and tile positioning in space are stored in a first xml
file. The list of tiff files composing the dataset is stored in another xml
file. This reader expects to be pointed to a file in the directory containing
the xml files.

What it does now:
- Open 5D datas, stitched on the fly. That is: if a plane is made of 4
  fields of 920x920 pixels arranged in a square, it will return a plane
  of 1840x1840 pixels.

Current limitations:
- OME metadata is not set yet.
- Only reads the first Area of the first Well yet.

CellVoyagerReader: warn if we have to open an unknown file version

I bet two smarties that the device we got (at the Pasteur imaging
facility) is going to be severely updated and that most of the
problematic XML tags will get fixed. Since I cannot foresee the future
that well, I put a warning to future users.

CellVoyagerReader: fix incorrect IDs found in the OME.XML file

As per Melissa comment.
The trouble is that this edit does nothing at all: putting back the ID
manually through the MetadataStore or through the OME MD is simply
ignored.

Do not prompt to update to the latest stable version if Fiji is used

The registry will still be contacted if the user has allowed it, but
repeated prompts to upgrade will no longer appear in Fiji.  The upgrade
prompts should remain in plain ImageJ.
