Raise an Exception if the column_data row_names of the alternative_experiments are not the same as those of the main experiment.

In Bioconductor's SingleCellExperiment class the colData rowNames of the altExps is expected to be that same as the colData rowNames of the main experiment. Currently in Bioconductor if this is not the case the offending colData rowNames are overwritten by those of the main experiment and a Warning is raised that in a future version this will raise an error instead.

Currently in BiocPy's SingleCellExperiment no checks occur whatsoever for identity between main and alternative_experiments column_data row_names.

I propose SingleCellExperiment of BiocPy should raise an Exception if the column_data row_names of the alternative_experiments are not the same those of the main experiment.
