Feature or enhancement

New quoting rules QUOTE_NOTNULL and QUOTE_STRINGS were introduced in#67230. But they only affect CSV writer, not CSV reader. I think that they should affect CSV reader in the same way as QUOTE_NONNUMERIC does.

• QUOTE_NOTNULL -- unquoted empty strings are returned as None.
• QUOTE_STRINGS -- unquoted empty strings are returned as None and unquoted numeric strings are returned as float.

It is perhaps too late to change this in 3.12, so it can be considered as a new feature in 3.13.
