Allow using Date as a value

[Rauttis]

Both pg and mysql allow you to pass Date instances as values and do the correct transformation for you.

This was allowed in sql-template-tag as well until the Value type was made more strict in d1fb92e.

Ah, thank you! This was my mistake, tried to make it stricter to avoid user error. Do you have any opinion on expanding types vs just making it unknown? I wasn't sure about the better approach here since technically anything could work but some things like a random class could be user error.

I like that there's some type safety there, but trying to support every use case people will have without just making it any/unknown is probably futile, since anything that can be stringified should be fair game.

Also thanks for the quick merge & release!
