patch 9.1.1459: xxd: coloring output is inefficient

Problem:  xxd prints color escape sequences for every octet
          even if the color doesn't change
Solution: use separate arrays for colors and text and only
          print escape sequences when the color changes
          (Emanuel Krollmann)

fixes: #15122
closes: #17535
