Speed Regression Benchmarking

I ran across this neat [repository](https://github.com/dandavison/chronologer) that uses [`hyperfine`](https://github.com/sharkdp/hyperfine) benchmarking suite to run tests over the Git history of a repository to find performance regressions.

Ideally, `from pwn import *` should be as fast as possible. It might be worth digging into benchmarking it with [`chronologer`](https://github.com/dandavison/chronologer) in order to find speed regressions.

Generally, regressions will be the result of early importing of large modules like `shellcraft` or `unicorn`.
