Related to issue #86 domain_specific_metric_calculations

One application of domain-specific metric calculations is to only compare metrics for those domains for which we are confident that the anatomical/manual labels and transcriptomic signatures align. To do that, we need to specify the confidence of each cell's label and it's suitability for use in domain-specific metrics.

We need to add an optional, numerical column, label_confidence, to labels.tsv. For now, it should only be used as a boolean, 0 for "too low confidence, don't use this label for metrics" and 1 for "high enough confidence to use this label for metrics". In the future, if we want to expand to numeric rankings between 0 and 1, we will need to define explicit criteria for each numeric ranking.

TODO:
Add the optional numeric label_confidence column to labels.tsv templates/documentation.

this column will be boolean instead of numerical
