Baseline benchmark for Flask served via gunicorn, for comparison against
http-nu.
```bash
pip install flask gunicorn
```
```bash
nu run.nu # run and display
nu run.nu --save # run and save to results.nuon
nu run.nu -w 8 # use 8 gunicorn workers
nu run.nu -c 100 -d 10s # 100 connections, 10 second duration
```
