Add color level option (-c) to control how to render colors for values
Color levels:
0: no colors (monochrome)
1: only color for addresses (yellow)
2: 1 + blue color for 00 (default if terminal supports color)
3: 1 + multicolor scheme by FrankSansC
from 0x20 to 0x7E included (printable characters) = white
0x00 = blue
0xFF = red
all other values = cyan
Note: this includes some commits from PR #30 to avoid merge conflicts
