Neuron metrics for all neurons in the hemibrain dataset

Description

This data.frame give metrics for neurons, such as cable_lengths and pre/post synapse numbers and densities, broken down by putative compartment. E.g. axons versus dendrite. This has been calculated for neurons across the hemibrain dataset, hemibrain:v1.0.1. The file used to generate this can be found in this package, as data-raw/hemibrain_split_all_neurons.R. Neurons were split as described by hemibrain_precomputed_splitpoints. Note that the first two columns, pre and post are generated by neuPrint. They differ from similar numbers in other columns of this data.frame because 'pre' is later given as the numbers of outgoing connections (not presynapses) and some erroneous pre/post synapses will have been removed by hemibrain_skeleton_check. Overlap locality is calculated as the 'overlap score' (Frechter et al. 2019, eLife) between a neuron's axon and dendrite.
