Instead of using "indexOf" you can use "lastIndexOf" which is a more robust
way to get the file extension. The only issue then is for file extensions
which themselves use a dot, e.g. ".ome.tif", but in most cases you do not
need to worry about these.

See also the "File.nameWithoutExtension" macro function.
