Run codespell on the entire codebase This tool detects and fixes common English spelling mistakes, with generally very few mistakes. Here is the command I used to generate this commit. There were a few changes that had to be done manually, and of course adding the ignore file: ```shell codespell -I .codespell-ignore -x .codespell-ignore -w ``` I didn’t add it to the CI, but this would be a good place for it.
