cannot get request.param if request.body lacks =

[itsumura-h]

import uri, httpclient

let data = {
  "name": "",
  "email": "aaa@example.com"
}
echo data.encodeQuery()
>> name&email=aaa%40example.com

var client = newHttpClient()
client.headers = newHttpHeaders({"Content-Type": "application/x-www-form-urlencoded"})
discard client.post("/", body=data.encodeQuery())

If set data in request.body, Jester cannot parse query because query style is not same key=value

# in Jester
echo request.params
>> {"name&email": "aaa@example.com"}

# expected output
>> {"name": "", "email": "aaa@example.com"}

I think it should be replaced like bellow

proc parseUrlQuery*(query: string, result: var Table[string, string])
    {.deprecated: "use stdlib cgi/decodeData".} =
  for row in query.split("&"):
    if not row.contains("="):
      result[decodeUrl(row)] = ""
    else:
      let rowArr = row.split("=")
      let key = rowArr[0]
      let val = rowArr[1]
      result[decodeUrl(key)] = decodeUrl(val)
