  • 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.

Let's check this running locally before merging - we might also be impacted by the the v10 changes in ads-admin (see https://github.com/brave/ads-serve/pull/5474#issuecomment-4004037437), even though the tests don't pick it up.
