Get rid of python warning in gCNV code.

Just a minor annoyance:

In the future this will be interpreted as an array index, `arr[np.array(seq)]`, which will result either in an error or a different result. mu_slice = mu_all[_get_singleton_slice_along_axis(mu_all, var_sample_axis, sample_index)] /home/slee/.pyenv/versions/anaconda3-5.3.1/envs/gatk/lib/python3.6/site-packages/gcnvkernel/io/io_commons.py:395: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated; use `arr[tuple(seq)]` instead of `arr[seq]`.

Hmm, just noting that I only see this when running in my local conda environment, and not with the Docker. 🤷‍♂️
