/**
 * Transparent Brotli response support.
 *
 * Adds Accept-Encoding: br to request and checks (and strips) for Content-Encoding: br in

  //   compress: 6
  //          b: 10
  //      after: { 11, 11, 22, 22, 33, 33, 00, 00, 00, 00, 00, 00, 77, 77, 88, 88 }
  //
  if (b != address.size) {
    if (compress == -1) return null // Address didn't have compression or enough groups.
    address.copyInto(address, address.size - (b - compress), compress, b)
    address.fill(0.toByte(), compress, compress + (address.size - b))
  }

 *  New: `OkHttpClient.Builder.minWebSocketMessageToCompress()` configures a threshold for
    compressing outbound web socket messages. Configure this with 0L to always compress outbound
    messages and `Long.MAX_VALUE` to never compress outbound messages. The default is 1024L which
    compresses messages of size 1 KiB and larger. (Inbound messages are compressed or not based on
    the web socket server's configuration.)

 * `server_max_window_bits`. This harms our ability to support these parameters:
 *
 *  * If `client_max_window_bits` is less than 15, OkHttp must close the web socket with code 1010.
 *    Otherwise it would compress values in a way that servers could not decompress.
 *  * If `server_max_window_bits` is less than 15, OkHttp will waste memory on an oversized buffer.
 *
 * See [RFC 7692, 7.1][rfc_7692] for details on negotiation process.
