ImageJ: disable file grouping when not reading from the filesystem

In particular, this disables grouping when reading over HTTP, as that is
at best extremely slow.

Fixes #12158.
ND2: adjust SizeC correction for small single plane datasets

Fixes #12222.
make: Convert variables to ant properties
QuickTime: reset stream if an invalid atom length is found

This is particularly necessary if the "header" is at the end of the file.

Also clarifies a variable name that's been annoying me for a while, and
fixes a couple of typos.

Fixes #12218.
