Encodes the response with the encoding that is requested by the client via the ``Accept-Encoding`` if it is among the provided encoders or rejects the request with an ``UnacceptedResponseEncodingRejection(supportedEncodings)``.
The response encoding is determined by the rules specified in RFC7231_.
If the ``Accept-Encoding`` header is missing then the response is encoded using the ``first`` encoder.
If the ``Accept-Encoding`` header is empty and ``NoCoding`` is part of the encoders then no
response encoding is used. Otherwise the request is rejected.
