Previously, we were allocating extra space for 'buckets'
to accommodate hash collisions, but this turns out to waste a lot of space
in large graphs.

Additionally, we are no longer allocating space for nodes ahead of time;
now, the nodes array will grow on demand, as edges are added.

This unlocks the ability to resize without creating a new intermediary AdjacencyList.

The (incorrect) assumption was that there should be the same node record count
after a resize of edges, but this is not necessarily the case; if there were
deleted edges before the resize, then there may be node records that will
also be deleted (by virtue of no longer having any edges connected to them)
as part of the resize.
