    Minor r'str' fix to vmodtool.py
    
    Python does not like having `\` characters followed by non-special characters, e.g. `\.` - but regex requires that. For this, python has "raw strings", e.g. `r'....'` - this way no `\` have any special meaning to python, only to the regex itself.  At least on my 3.12 Python it refused to work without it.
