Verify SE holiday calendar

[arkid15r]

SE has every Saturday included as a public holiday, even though only the banks are closed. Is this intended? If so it is at least misleading as BANK is not the primary category if I understand it correctly.

Actually, it's every Sunday we have as public holiday (with special arg include_sundays=True). I've always wondered how Sundays in Sweden differ from Sundays in other countries (where they are also days off). As far as I understood, the reason for this difference is that

In Sweden, public holidays are defined in the Swedish Constitution as a Sunday, or another day in a list of public holidays

(from Wiki, machine translation to English)

Is this a enough reason for us to include all Sundays in the list of holidays? Maybe we could at least set include_sundays default value to False? (exactly how it's done for Norway now)
