Discover inconsistent whitespace

Bad formatting can sometimes sneak into code. Incorrect whitespace is especially tricky to notice, even with the `editor.renderWhitespace` setting turned on. While this should ideally be dealt with using a code formatter like prettier, there are some occasions where this is not possible. To avoid the embarrassment of checking in code with mixed indentation or trailing whitespace, I've created an extension that highlights these issues.
