skal 2bcad89b4c allow some more stdin/stout I/O
* allow reading from stdin for dwebp / vwebp
 * allow writing to stdout for gif2webp

by introducing a new function ExUtilReadFromStdin()

Example use: cat in.webp | dwebp -o - -- - > out.png

Note that the '-- -' option must appear *last*
(as per general fashion for '--' option parsing)
