Return status and header on HTTP error

[GeckoEidechse]

When performing an HTTP request, this returns the status code and headers of the response to help with figuring out why the request failed.

Mainly needed for #84 to check the response of the API in case of failure to check for ratelimit info etc.

Usage example

try
{
    authServerResponse = await asyncHttp.request( {
        method: "GET",
        host: "example.com",
        port: 80,
        path: "/example"
    } )
}
catch (response_object)
{
    console.log(response_object)
}

Gives on error

{
  statusCode: 200,
  headers: {
    date: 'Tue, 09 Aug 2022 21:39:23 GMT',
    'content-type': 'application/json; charset=utf-8',
    'content-length': '41',
    'access-control-allow-origin': '*',
    'example-rate-limit-remaining': '42'
  }
}

Currently existing functions do not try to reference this object so should not break existing calls to asyncHttp.request() in case of HTTP error.

seems fine to me

For now, we only need to access status/headers when request fails, this PR answer the need. LGTM
