The Codespell checker is saying we should replace "files'" with
"file's", but this is not a real issue since the single-quote on the end
is being used as a quote and not an apostrophe. Let's tell Codespell to
ignore this.
* Fix a typo
* Add codespell action
* Fix lots of spelling errors
* Fix a few more spelling mistakes
* Add an ignore words list
* s/parsable/parseable/
* Don't touch the third party files
* Cloneable is the preferred C# term
* Copyable is the preferred C++ term
* Exclude some more words and folders
* Revert "s/parsable/parseable/"
This reverts commit 534ecf7675.
* Revert unparseable->unparsable corrections
* Skip more locations and add some ignore words that haven't been merged yet
