Gracefully handle ZEROFILL flag when given a IPv6 address #383
Description
I am in the process of upgrading netaddr from 0.10.1 to 1.2.1, my Python version is 3.12.3.
In older versions the netaddr.ZEROFILL flag was ignored when a IPv6 address was given:
# netaddr==0.10.1
>>> import netaddr
>>> ip = netaddr.IPAddress('2600:1f18:631e:2f85:93a9:f7b0:d18:89a7', flags=netaddr.ZEROFILL)
>>> ip
IPAddress('2600:1f18:631e:2f85:93a9:f7b0:d18:89a7')In the current release it throws an ValueError:
# netaddr==1.2.1
>>> import netaddr
>>> ip = netaddr.IPAddress('2600:1f18:631e:2f85:93a9:f7b0:d18:89a7', flags=netaddr.ZEROFILL)
