Support size limit of response body?

[ZigHuang]

Hi👋
I am using this library recently, and found that the configuration does not seem to support the length limit on the response body?
As background, I'm using this library to make a lot of http requests and find that the bandwidth usage is more than I expected.

I currently set DisableAutoReadResponse() and use io.LimitReader() it to solve this problem.

Thanks for the suggestion. This is a reasonable feature request — a built-in MaxResponseSize option would be more ergonomic than manually combining DisableAutoReadResponse() with io.LimitReader().

As you noted, the current workaround is:

client.SetCommonResponseOptions(&req.ResponseOptions{
    DisableAutoReadResponse: true,
})
resp, err := client.R().Get(url)
io.CopyN(dst, resp.Body, maxSize)

Marking as enhancement / priority:low. Contributions are welcome.
