OUI constructor does not support inputs it claims to support

[JonathonReinhart]

The OUI constructor OUI.__init__ claims to support accepting a regular old MAC address as an input:

Also accepts and parses full MAC/EUI-48 address strings (but not MAC/EUI-48 integers)

netaddr/netaddr/eui/__init__.py

Lines 64 to 72 in e84688f

	def __init__(self, oui):
	"""
	Constructor
	:param oui: an OUI string ``XX-XX-XX`` or an unsigned integer. \
	Also accepts and parses full MAC/EUI-48 address strings (but not \
	MAC/EUI-48 integers)!
	"""
	super(OUI, self).__init__()

It handles a hyphen-separated OUI okay:

>>> OUI('f4-6d-04')
OUI('F4-6D-04')

But doesn't work as advertised in the doc string with any of the formats (supported by EUI parser):

Bare MAC:

>>> oui = OUI('f46d04112233')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/netaddr/eui/__init__.py", line 101, in __init__
    raise NotRegisteredError('OUI %r not registered!' % oui)
netaddr.core.NotRegisteredError: OUI 'f46d04112233' not registered!

Hyphen-separated MAC:

>>> oui = OUI('f4-6d-04-11-22-33')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/netaddr/eui/__init__.py", line 101, in __init__
    raise NotRegisteredError('OUI %r not registered!' % oui)
netaddr.core.NotRegisteredError: OUI 'f4-6d-04-11-22-33' not registered!

Colon-separated MAC:

>>> OUI('f4:6d:04:11:22:33')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/netaddr/eui/__init__.py", line 83, in __init__
    self._value = int(oui.replace('-', ''), 16)
ValueError: invalid literal for int() with base 16: 'f4:6d:04:11:22:33'

FWIW I'm testing on version 0.7.19 (Debian bullseye) but the code I've linked to is in master.

There are a number of TODOs here:

netaddr/netaddr/eui/__init__.py

Lines 79 to 83 in e84688f

	if isinstance(oui, str):
	#TODO: Improve string parsing here.
	#TODO: Accept full MAC/EUI-48 addressses as well as XX-XX-XX
	#TODO: and just take /16 (see IAB for details)
	self._value = int(oui.replace('-', ''), 16)
