allow escaping inside quotes
RFC5322 allows for escapes using \ inside quotes. Otherwise, headers
such as
From: "\"Doe, John\"" <op>
get mangled as "\"Doe@localhost, John\" <op> since \ would be treated as
ordinary character and not the escape for the quote.
Bug reported by TobiasEgg on the OpenSMTPD-portable github repository.
