many typos in duckencoder.py

481-482
-p, --pastthru Read script from stdin and print result on stdout (ignore -i, -o)
-r, --rawpassthru Like passthru, but input is read as STRING instead of duckyscript

498-500 (and many other ones)
rawpassthru = False
try:
opts, args = getopt.getopt(argv, "hi:o:l:pr", ["help", "input=", "output=", "language=", "passthru", "rawpassthru"])

524-531:
elif opt in ("-p", "--passsthru"):
[...]
elif opt in ("-r", "--rawpasssthru"):

and I probably missed many other ones ...
