od already has multiple options for specifying the base of the offset
independently from the base of the characters, so there is indeed
precedent (and if we DO enhance cmp, I'd want to use the same short and
long option names of -A/--address-radix for the offset portion, but I'm
not sure what we'd copy for the byte portion, as -t/--format, or even
-b, aren't quite right).

Meanwhile, these days, it's pretty easy to use the shell to convert
between bases (using $(()) converts any base to decimal, and printf
converts decimal to any base), so I'm not sure if it's worth bloating
cmp to have the same flexibility as od.
