This DB was created with the foreign key constraint `PRAGMA` enabled and a bunch of column-level `CHECK` constraints.  Is this an expected behavior? Should one not try to index foreign keys if FK constraints are already being enforced within the DB?

I'm also noticing that the size of the DB after FK indexes have been added went from 483MB to 835MB, which seems like a much bigger jump than when I've done this previously.

It would be nice to have an example in the docs on how to filter by date range using `rows_where()`. 
This doesn't seem to work:
```
table.rows_where('datetime(created) between datetime(""2021-10-31T17:29:59.277428-04:00"") AND datetime(""2021-11-01T03:44:04.544651+00:00"")')

I could probably just use `db.query()`, which works for the above, but it would be nice if I could pass in `datetime` objects in `rows_where()`.

Here is an example of how to query the data after the script has run:
```
select notes.*,
	(select group_concat(tag) from notes_tags where notes_tags.note_id=notes.id) as tags
from notes;
```

My .enex source file is 3+ years old so I am assuming the structure hasn't changed.  Interestingly, my _notebook names_ show up in the _tags_ list where the tag name is prefixed with `notebook_`, so this could maybe help work around the first limitation mentioned in the [evernote-to-sqlite blog post](https://simonwillison.net/2020/Oct/16/building-evernote-sqlite-exporter/).
