In previous implementation `client` package provided access to nested response fields as pointers to them. This caused clients to handle nil cases even when the field presence in the response is required. Avoid returning pointers to required fields in response getters. This also reduces reference counter load and allows fields to be decoded directly without additional assignment. Signed-off-by: Leonard Lyubich <leonard@nspcc.ru>
