iio_reg only addresses reg 0x0 when run on Pluto

See post: https://ez.analog.com/adieducation/university-program/f/q-a/539472/plutosdr-v0-32-iio_reg-can-t-read-registers

I can repeat this on v0.32 firmware.

I think Michael fixed that - what version of libiio is on that?

I can replicate on master, but not on the release.

This was the fix - https://github.com/analogdevicesinc/libiio/commit/f75ced2ab5690a3da72c2f83947a854a9f96871e

Can you try to specify the address in decimal instead of hex?

Libiio version 0.21 was released Jun17, my fix was committed July31. So our latest release is still broken.
