[simojo]

1. Make sure the title is descriptive of what the PR includes. Don't mention issue names/numbers; save that for the description.

2. List the names of those who contributed to the project. @simojo

3. Link the issue the pull request is meant to fix/resolve. Closes #29

4. Describe the contents and goal of the pull request. This PR adds pre-commit hooks. By running poetry run task pre-commit-install, a developer can easily configure pre-commit hooks to be installed for their system. The pre-commit commands are defined in .pre-commit-config.yaml, which I will put here:

# configuring pre-commit hooks for chasten.
# this ensures users do not commit problematic code
repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v4.5.0
    hooks:
    - id: check-ast
      files: '\.py$'
    - id: check-case-conflict
    - id: check-merge-conflict
    - id: forbid-submodules
    - id: trailing-whitespace

  - repo: local
    hooks:
      - id: fix-linting
        files: '\.py$'
        name: Fix Linting
        entry: poetry run task lint --fix
        language: system

5. Will coverge be maintained/increased? This does not affect coverage.

6. What operating systems has this been tested on? How were these tests conducted? This has been tested in NixOS 22.11.2301.cff83d5032a

7. Include a code block and/or screenshots displaying the functionality of your feature, if applicable/possible.
