[Feature] Add path and default parameter in .json()

[perklet]

Is your feature request related to a problem? Please describe.
It is very common that we only want part of the json response. Using jsonpath, we can directly select the particular part.

Describe the solution you'd like

from curl_cffi import requests

r = requests.get("https://example.com/api/users.json")

# before
try:
    users = r.json()["data"]["users"]
except KeyError:
    users = []

# after
users = r.json(path=".data.users", default=[])

Describe alternatives you've considered
N/A

Additional context
The dependencies should be optional, like pip install curl_cffi[extra].
