Passing list of IPRange objects to IPSet Fails

[shepherdjay]

While it appears you can mix/match a list of IPNetwork and IPAddress objects into IPSet for construction you cannot pass a list that contains an IPRange object. This leads to an asymmetry when handling large datasets that contain multiple of each type.

Working Examples

>>> my_set = IPSet([IPNetwork('10.0.0.0/24'), IPNetwork('192.168.1.0/24')])
>>> my_set
IPSet(['10.0.0.0/24', '192.168.1.0/24'])

>>> my_set = IPSet([IPNetwork('1234::/32'), IPAddress('192.0.2.0')])
>>> my_set
IPSet(['192.0.2.0/32', '1234::/32'])

>>> my_set = IPSet(IPRange('10.0.0.0', "10.0.1.31"))
>>> my_set
IPSet(['10.0.0.0/24', '10.0.1.0/27'])

Attempts to add any range objects if they are part of a set fail. Even if all objects in list are range type.

>>> my_set = IPSet([IPRange('10.0.0.0', "10.0.1.31"), IPRange('192.168.1.0', '192.168.1.5')])

TypeError: unexpected type <class 'netaddr.ip.IPRange'> for addr arg

This same error type is reported when adding a mixed set of object types if one of those types include an IPRange or when passing a list of a single IPRange object.

Looks like a legitimate bug, needs fixing.
