visual dump, dump hex bytes in a sane way.

In Unix/Linux OD wants to dump out hex bytes in little endian format.
What this means in the output of the hex bytes is swapped.

Notice the first line, 4047 is really  0x47 0x40 but each pair of bytes is swapped.

$ od -xc dump-263.ts | head

So I have created a little script vd (yea get over it, it stands for visual dump)

$cat vd
od -txC -c -N 128 $1

$vd dump-263.ts
