Add very basic support for .edu domains

[wrongecho]

I don't really code in Python, but this PR adds some basic support for .edu domains to parse the creation/expiration dates. Still requires additional later work for other fields.

Currently:

{'domain_name': 'SRU.EDU', 'registrar': None, 'whois_server': None, 'referral_url': None, 'updated_date': None, 'creation_date': None, 'expiration_date': None, 'name_servers': None, 'status': None, 'emails': None, 'dnssec': None, 'name': None, 'org': None, 'address': None, 'city': None, 'state': None, 'registrant_postal_code': None, 'country': None}

With this PR:

{'domain_name': 'SRU.EDU', 'creation_date': datetime.datetime(1993, 1, 20, 0, 0), 'expiration_date': datetime.datetime(2024, 7, 31, 0, 0)}
