feat: add max reponse body limit

[trim21]

Client not will be able to check resposne body size limit.

If server return a large response than expected, it will discard the response and return a err ErrResponseBodyTooLarge.

c := Client().SetResponseBodyLimit(1024*1024*1024) // do not allow body larger than 1GiB
res, err := c.R().Get(...)
if err != nil{
  if errors.Is(err, resty.ErrResponseBodyTooLarge){
    ...
  }
}

close #819

@trim21 Thanks for creating a PR.

I wanted to confirm before I start reviewing it. If you don't mind, your use case is to fail the request if the response body size exceeds the specific size. Can you update the PR description to one use case and its example?

I'm not sure size limit should be int or int64.

It's a length limit of []byte, and len([]byte) is int, so it would make more sense to be int?

@trim21 Yes, for size limit, keep type int
