Better configuration support

oxlint -c ./eslintrc.json

will use the rules field for rule configuration, as documented in ESLint's documentation.

Unfortunately, only the json format is supported right now.

The extends field will not take effect; normal -D and -A flags still apply.

To add / remove / configure a rule:

{
  "rules": {
      "no-empty": "off", // removes the rule
      "no-empty": "error", // adds the rule
      "no-empty": ["error", { "allowEmptyCatch": true }]` configures the rule
  }
}
