Investigate and improve allocation behavior of collapse-perf #44

Since the project is fairly recent I assume it's benched on a recent version of Rust (or even nightly, does Criterion require nightly?) That means it's using the system allocator, and IIRC flamegraph munging is a lot of string munging and other allocation-heavy tasks, jemalloc could well have an edge.
