Parses a string with lines delimited with CRLF into an Array of SingleResponseHeaders
objects. libCURL supplies us multiple responses in sequence, so if we encounter multiple redirect or operate through a proxy - that adds ConnectionEstablished status at the beginning of the response - we need to account for parsing multiple response headres and potentially preserving them.
@param [String] the string of headers, with responses delimited by empty lines. All lines must end with CRLF @return Array<SingleResponseHeaders>
