Add support for CalibratedClassifierCV algorithm

[mChowdhury-91]

We have just started using explainerdashboard in production and want to add support for new algorithms.
For one of the model training we were using CalibratedClassifierCV algorithm, and the explainerdashboard doesn't support this explainer by default.
The shap value calculations happen using default KernelExplainer which takes a lot of time(approx 3hrs for 2000+ dataset).
Is there a way we can support this algorithm in ExplainerDashboard so that calculations happen fast?
