Add server ip address to response object

[embeddinglayer]

Ideally the response object should include the established server ip. Curl already offers that which is a better alternative to opening an entirely new socket connection to resolve that data.

import curl_cffi.requests as requests

resp = requests.get("https://example.com")
print(resp.ip)

Ideally the response object contains more data for the underlying connection such as CURLINFO_CERTINFO and CURLINFO_TLS_SESSION

Interesting idea! However, it seems that there is no such const as CURLINFO_NUM_CERTS.

Yeah, that code was unintentional looks like vs-code hadn't persisted to disk when I committed. Just removed it, I'll push the full code for certs in a later commit.

We need one or two unittests to make sure that this patch works as expected. Feel free to add them now or leave it there and I will add them later.
