missing `gauss_ci_test` and `gauss_ci_suffstat` from utils module

[klai001]

Hi
ive installed causaldag but i realised gauss_ci_test and gauss_ci_suffstat are no longer in utils module
is there a source code archive version of them?
thanks

I believe this commit has the requirements for UT-IGSP, and you need to install numba: https://github.com/uhlerlab/causaldag/tree/734939695f8561b2aceac38c3394e0715bf27f56

For anyone in 2026 with the same issue, I found that the pinned PyPI version also works:
pip install causaldag==0.1a136
