MINOR: sample: allow integers to cast to binary

Doing so finally allows to apply the hex converter to integers as well.
Note that all integers are represented in 32-bit, big endian so that their
conversion remains human readable and portable. A later improvement to the
hex converter could be to make it trim leading zeroes, and/or to only report
a number of least significant bytes.
