Fix mismatched keys in rdap and whois methods

[pogzyb]

The rdap_domain method uses whodap's to_whois_dict method behind the scenes. This library returns slightly different keys for the whois dictionary that asyncwhois does not.

For example:

import asyncwhois

w = asyncwhois.whois_domain("google.com")
r = asyncwhois.rdap_domain("google.com")

w_keys = w.parser_output.keys()
r_keys = r.parser_output.keys()

# see mismatches
print([k for k in r_keys if k not in w_keys])
print([k for k in w_keys if k not in r_keys])

The task is to write a static function in the DomainLookup class:

@staticmethod
def _convert_whodap_keys(parser_output: dict) -> dict:
    # handle mismatched keys
    return parser_output

The above function should be used in the rdap_domain and aio_rdap_domain functions of DomainLookup

whois_dict = response.to_whois_dict()
_self._parser = _self._convert_whodap_keys(whois_dict)
return _self
