Merge #2878: [Lint] lint spelling

27b0e0c [Lint] lint spelling (Fuzzbawls)

Pull request description:

  Spelling errors can be embarrassing when seen by outside parties, even if they have no impact on the program's operation. This utilizes [Codespell](https://github.com/codespell-project/codespell) to find common spelling errors during the CI's lint stage and will throw an error if any such misspellings are found.

  A whitelist text file is provided to ignore known false positives, and the lint script ignores any third party dependencies as well as translation files.
