Closes #266

The following were performed in this PR:

• Add pre-commit hooks
• Applied hooks to repo (Many file changes)
• Update CI to include auto-application of pre-commit

Manually modified files:

• .clang-format-ignore
• .github/CONTRIBUTING.md
• .github/scripts/auto-formatter.sh (removed)
• .github/workflows/CI.yml
• .github/workflows/_CI_coverage.yml
• .github/workflows/_CI_update.yml
• .github/workflows/_precommit.yml
• .pre-commit-config.yaml
• client/python/vdms/init.py
• README.md

Remaining files were modified after applying hooks

After this is merged, users can manually setup to apply to all commits:

# Initial setup (first-time)
pip install pre-commit
pre-commit install

# Manually check files
pre-commit run --all-files

But as a safe-guard, it is also included in the CI process. In cases where changes are needed, the CI job will fail. If pre-commit can automatically fix issues, the CI will restart with new changes. If pre-commit cannot fix any issues, user should fix requested issues and CI will start once PR is updated.
