• Implement targeted builds for ES modules, CommonJS, and browser (global assignment).
• Add CI workflow.
• Add type declaration import tests.
• Remove BigNumber.DEBUG, so the behaviour is now always as if it was true:
  • throw on invalid input instead of returning NaN.
  • always validate the c, e, and s properties of objects passed to isBigNumber
• Don't call toString on any arbitrary object passed to the constructor.
• Require a BigNumber value to be a string if a base is also passed.
• Add toObject prototype method which returns a plain object with c, e, and s properties.
• Remove .npmignore, as files in package.json is used. Add .gitignore.
• Normalise line endings and add .gitattributes.
• Add typescript to devDependencies.
