analytics/counts: add simple counts on graphs
This adds a module and a function to aggregate some counts about characteristics of graphs, accumulating the node count by rank, the number of nodes by category, the number of leaps, the summed sized of the exclusive parts.

analytics/main: add CLI entry point for analytics counts
This allows the graph counts to be called through the CLI so that they can be computed on the reference graphs of vcsgraph-reference.
