Fix string escaping in location tool

Python 3.12 started to warn on an invalid string escape sequence:

$ location list-networks-by-as --format ipset 1
/usr/bin/location:583: SyntaxWarning: invalid escape sequence '\d'
  m = re.match("^AS(\d+)$", object)
IpsetOutputWriter requires family being set

This patch fixes the warning as well as the regular expression by
using a raw string.
