Don't correct iif to if

[tekumara]

because iif is a sql function name (eg: in sqlite)

I think we should still correct it by default because I think in codebases in general it's likely to be a typo. If your codebase uses that SQLite function, you can just add it to default.extend-identifiers.

Or detect if the file is SQL, or part of a string SQL query.

btw with #793 we more easily support per-filetype dictionaries (see #794).

If the sql file type would catch enough of these cases, I'm fine if someone adds that into there.

We currently nor do I have plans for detecting nested languages, so us handling SQL queries inside of files is unlikely to happen
