Research direction
Start with src/rapids_singlecell/preprocessing/_kernels/_mean_var_kernel.py and src/rapids_singlecell/preprocessing/_kernels/_sparse2dense.py, then compare the current kernels with the CuPy support introduced in #51. Done means the sum, mean_var, and related operations are faster with the custom kernels.
