Add ESLint configuration and scripts

[bthomas2622]

This pull request introduces linting setup to the project, enhancing code quality and consistency.

• Adds ESLint configuration: A new .eslintrc.json file is created, specifying the environment, extending eslint:recommended, and defining rules for indentation, linebreak style, quotes, and semicolons.
• Updates package.json:
  • Adds eslint and related plugins (eslint-config-standard, eslint-plugin-import, eslint-plugin-node, eslint-plugin-promise) to devDependencies.
  • Introduces two new scripts, lint for checking issues and lint:fix for automatically fixing issues.
