So now the following forms are supported:
$ ./scripts/crc32c.py -x 41 42 43 44
fb9f8872
$ ./scripts/crc32c.py -s abcd
fb9f8872
$ echo '00: 41 42 43 44' | xxd -r | ./scripts/crc32c.py
fb9f8872
Hopefully this will make crc32c.py more useful. It hasn't seen very much
use, though that may just be because of the difficulty marshalling data
into a format crc32c.py can operate on.
That and dbgblock.py's -x/--cksum flag covering one of the main use
cases.
