Slidebook TIFF: prevent NPEs when metadata is missing
Slidebook TIFF: close open file handle in TiffParser
PNG: fix support for images with fewer than 8 bits per pixel

Fixes #10887.
Metamorph TIFF: populate PhysicalSizeZ

Fixes #10884.
Leica LIF: parse PhysicalSizeZ from one more place

Fixes #10843.
DNG: fix type checking to prevent picking up Photoshop files
SVS: disable file grouping

It's very common to have similarly-named files in the same directory
that have very different dimensions.  To prevent weird problems with grouping,
and because the workflow of dealing with slides means that grouping
isn't really necessary, it is now disabled.
Slidebook TIFF: make type checking more rigorous
CellWorx: do not pick up .pnl/.tiff files if file grouping is turned off

Noticed by Stéphane Dallongeville.
Leica LIF: a few more physical size and position fixes

Noticed by Olivier Burri:

CellWorX: one more type checking fix

This allows the log files to be picked up if isGroupFiles() returns false.
Leica LIF: prevent indexing issues if an invalid field position is found
AVI: prevent reading beyond the end of the file

Fixes #10720.
Allow use of ImageJ 1.47q and later

See #10837.  Only 1.47o and 1.47p are excluded now.
Leica LIF: fix channel metadata for tile scans

Fixes #10952.

mdb: fix page swapping bug when reading column text values

The page buffers are swapped at the beginning of the read, and are
expected to be swapped back at the end of the read.  This was happening
if the read was successful and the value was valid, but not if the value
was invalid.

Fixes #10942.
mdb: only swap the buffers back if the memo length is zero

See c68c915d2430c80080907f46a90d5ea203cfd117.  Swapping on a memo with
length greater than 0 has the potential to introduce an infinite loop.
CellR: fix subtle issues in close() and openBytes

close() now clears all variables, and openBytes now does proper
parameter checking.  The former may help with the problem of incorrect
pixel data when importing certain CellR datasets into OMERO (see PR 529).

CellR: prevent invalid files from being added to the used files list
CellR: trim the image names before sending them to MetadataStore
