This feels like to could be a one-liner... (different output to yours)
python3 -c 'W = 16; import sys, itertools as it; sum(print("
".join(map("{:02x}".format, b))) or 0 for b in it.takewhile(bool,
map(sys.stdin.buffer.read, it.repeat(W))))'
or, with offset numbers and an ASCII column,
python3 -c 'W = 16; import sys, itertools as it; sum(print(f"{W*i:08X}
", " ".join(map("{:02x}".format, bb)).ljust(3*W+1), "".join(chr(b) if
0x20 <= b <= 0x7e else "." for b in bb)) or 0 for i, bb in
enumerate(it.takewhile(bool, map(sys.stdin.buffer.read, it.repeat(W)))))'
