Summary: Previously looking up a particular node in a histpack required a bisect to find the file section, then a linear scan to find the particular node. If you needed to look up the latest 3000 nodes one by one, that involved 3000 linear scans, many of which traversed the same nodes over and over. This patch adds additional index at the end of the current histidx file. In a future patch, we will change getnodeinfo() to use this index instead of the linear scan logic. Test Plan: Ran the tests. I haven't actually verified that the data in these indexes is correct. My next patch will add logic that reads these indexes and will add tests around it. I won't land this until I've confirmed it's correct.
