Apparently i2cdump doesn't support a range in "i" mode. I considered
adding a range to i2cdump in all modes but:
- i2cdump code is a more complicated
- Not all devices interpret i2c bulk read as a register range. Reading X
bytes from register Y can be different from reading registers from X to X+Y.
