get experiment function

[WhyYouNeedMyUsername]

At present, the Decanter AI SDK does not offer the "get experiment" function. Here's how I implemented the functionality using the API as an illustration.

res = requests.get(
    f"{client.api.url}experiment/642fcc1c8312e3074c6f64da",
    headers=client.api.auth_headers,
    verify=False,
)

update:
The new functionality include model_name, model_id, attributions, metrics, best_model_id
