Please run `pre-commit install` before making commits

Hi SeongJae,

I've added pre-commit hooks before at #62, but it seems that you didn't install its hooks.

So the current pre-commit hooks complain a lot as follows.

$ pre-commit run -a
check yaml...............................................................Passed
fix end of files.........................................................Failed
- hook id: end-of-file-fixer
- exit code: 1
- files were modified by this hook

Fixing src/_damo_print.py

trim trailing whitespace.................................................Passed
isort....................................................................Failed
- hook id: isort
- files were modified by this hook

It'd be better to run pre-commit install before making commits from now on unless you don't like these kind warnings.

Thank you for this kind report, Honggyu! I wanted to learn more about the pre-commit hook and use it, but unfortunately couldn't find time for that so far. Let me try more. I will fix the reported issues first.

I successfully installed pre-commit on my development machine and fixed all warnings.

Thanks. Maybe we can think about adding some description about pre-commit at CONTRIBUTING file just like https://github.com/namhyung/uftrace/blob/master/CONTRIBUTING.md#coding-style.
