`formParameters` doesn't work

I have to construct the query params my self, if I use formParameters on a request it doesn't seem to work (I get 404).

  def get(uri: String, params: Map[String, String]): Future[Response] = {
    val formParams: List[FormParameter] = params.map(kv => FormParameter(kv._1, kv._2)).toList

    val paramSuffix: String = if (params.isEmpty) "" else s"?${params.map(kv => kv._1 + "=" + kv._2).mkString("&")}"

    Future {

      // Works
      http(
        GET(uri + paramSuffix)
      )

      // Not work
      http(
        GET(uri)
          .formParameters(formParams: _*),
      )
    }
  }

Also FormParameter seems like a fairly redundant type, could just use Map[String, String]

@samthebest I'd be happy to pair with you to explore this.

FormParameter is part of naive-http's domain (although not as central as Request, Response, etc), Map[String, String] is not.

Map[String, String] may very well be a fine underlying encoding, it's a terrible representation/api as it has nothing to do with form parameters. The domain of http deserves to be first class (especially in a library about http !), whilst also being careful not to gatekeep / be rigid / drown in NIH.
