Automate formatting/linting

[j127]

Automate formatting/linting with a git hook or similar method.

• prettier.js
• flake8 (or whatever)

For Prettier, there appears to be 5 choices on when the changes may occur, do you have a preference?

Option 1 looks like it would be easy for people to use without having to think about it, unless you think another one would be better.

I tried it in the other data repo and it works well.

I overwrote their prettier command with a custom shell script (./format_json.sh) that runs on every commit.

    "devDependencies": {
        "husky": "^4.3.0",
        "lint-staged": "^10.5.1",
        "prettier": "^2.2.0"
    },
    "husky": {
        "hooks": {
            "pre-commit": "lint-staged"
        }
    },
    "lint-staged": {
        "*.--write": "./format_json.sh"
    }

Edit: ↑ that actually might not be working correctly.
