WIP: throughput-oriented walredo benchmark

Browse Source 
duplicates some code from bench_walredo.rs

build using `cargo bench --benches walredo_throughput`
then use like so:

target/release/deps/walredo_throughput-38cf92dd3160bcbd  --managers 100 --clients-per-manager 1

(need to figure out harness = false stuff)

yielded some interesting flamegraphs & tracing overhead, fixed it in
this commit; flamegraphs in my notion
