I've switched to using the ipaddr module in pyspf.  I could have 
expand_iplist() return a list of IPNetwork from that module.  The 
IPNetwork ctor automatically handles converting IP6 addresses from 
either 16 byte binary or string format, and collapse_address_list() will 
combine adjacent networks.  A new in_address_list would check an ip 
against the output of expand_iplist().  This would prevent any new 
dependencies when using the old iniplist() function.  What do you think?
