Add code lint

[shadowv0vshadow]

Add .pre-commit-config.yaml for lint in git commit. And add lint CI for lint.

If you want use lint tool, you should install pre-commit. i add pre-commit in requirements.txt.

Github action:

name: Lint code

on: [push, pull_request]

permissions:
  contents: read

jobs:
  lint:
    runs-on: ubuntu-20.04
    timeout-minutes: 10

    steps:
    - uses: actions/checkout@8ade135a41bc03ea155e62e844d188df1ea18608 # v4.1.0
    - name: Set up Python
      uses: actions/setup-python@82c7e631bb3cdc910f68e0081d67478d79c6982d # v5.1.0
      with:
        python-version: "3.x"
    - name: Run pre-commit
      uses: pre-commit/action@646c83fcd040023954eafda54b4db0192ce70507 # v3.0.0

Maybe We can also use pyproject.toml manage project later
