Summary:
BonsaiChangesets are rarely mutated, and their maps are stored in sorted order,
so we can use `SortedVectorMap` to load them more efficiently.
In the cases where mutable maps of filechanges are needed, we can use `BTreeMap`
during the mutation and then convert them to `SortedVectorMap` to store them.

Summary:
Add a microbenchmark for deriving data with large directories.
This benchmark creates a commit with 100k files in a single directory, and then
derives data for that commit and 10 descendant commits, each of which add,
modify and remove some files.
