arguments like --extended do not work

[ChristianAtSIE]

Hey,

I see that changing the bit-length is now supported (https://github.com/ChalkElec/write-edid/blob/master/write-edid.sh#L37), but if I call the script with '--extended' it throws: 'write: unrecognized option '--extended'

Changing line 22 (https://github.com/ChalkElec/write-edid/blob/master/write-edid.sh#L22) to ARGS=$(getopt -o "bhse" --longoptions "binary,hexadecimal,short,extended" -n "$PROGRAM_STRING" -- "$@") || exit works for, at least for the '--extended' bit, but I think it should also work for '--short'.

And in general thanks for the nice script.
