Add GPU-support for Kernel-based Conditional Test

[lmz123321]

Hi, thanks for your great work.

For causal discover in continous variables, a frequently used conditional independence test is Kernel-based Conditional Independence Test [1]. It is available in many causal discovery tooboxed written in R.

Do you plan to add a GPU support of this test? Many thx.

I am also very interested in work extending GPUs to work with continuous features/nodes.
