title: Scala circe decode Map[String, String] type
body: <p>I have a <strong>Map[String, String]</strong> object with I want to use as json. I have written an encoder for this type:  </p>
  
  <pre><code>implicit val encodeMap: Encoder[Map[String, String]] = new Encoder[Map[String, String]] {
  override def apply(values: Map[String, String]): Json = {
    values.toList
      .map(pair =&gt; Json.obj(
        (pair._1, pair._2.asJson)
      )).asJson
  }
  }
  </code></pre>
  
  <p>In addition to encoder, I need a decoder, but I don't have an idea how to write it. My best try so far:  </p>
  
  <pre><code>implicit val decodeMap: Decoder[Map[String, String]] = new Decoder[Map[String, String]] {
  final def apply(c: HCurser): Decoder.Result[Map[String, String]] = ???
  
  }
  </code></pre>
  
  <p>Pretty basic, but I don't really know how to get into this problem.<br>
  Thanks!</p>
