add support multipleContent types

[piworkacc]

Hello everyone Previously, there were plans to add support multipleContent types.

I expected it to be not only for the request but also for the response.

Right now, there is still the behavior where I always expect res.json() in the response.

https://github.com/kubb-labs/plugins/blob/44b8bb2588ac9940441405c31c6316bfb4333110/packages/plugin-client/templates/clients/fetch.ts#L89

And our project now has not the best workaround, but a working one...

const parseResponse = async (response: Response, responseType?: RequestConfig['responseType']): Promise<unknown> => {
  if ([204, 205, 304].includes(response.status) || !response.body) {
    return {};
  }

  if (responseType) {
    switch (responseType) {
      case 'json':
        return await response.json();
      case 'text':
        return await response.text();
      case 'blob':
        return await response.blob();
      case 'arraybuffer':
        return await response.arrayBuffer();
      case 'stream':
        return response.body;
      case 'document':
        return await response.text();
      default:
        return await response.json();
    }
  }

  const contentType = getContentTypeFromHeaders(response.headers);

  if (contentType) {
    if (contentType.includes('application/json') || contentType.includes('text/json')) {
      return await response.json();
    }
    if (contentType.includes('text/')) {
      return await response.text();
    }
    if (contentType.includes('image/') || contentType.includes('application/octet-stream')) {
      return await response.blob();
    }
  }

  const text = await response.text();
  if (!text) {
    return {};
  }
  try {
    return JSON.parse(text);
  } catch {
    return text;
  }
};

I admit that I don't understand everything about the client.ts fetch.ts and @kubb/client etc. But I just want to discuss how best to implement this, and in general, are there any plans for this and what is the best way to proceed?
