Add 'Yesterday' and 'Tomorrow' buttons

To take you to that day.

To check other dates, put ?date=somedate at the end, for example:

• https://whyaretheflagsup.github.io/?date=1-may-2015
• https://whyaretheflagsup.github.io/?date=Dec-6-2020

hello. may i help to fork this project?

[hugovk]

Hello, you may, thanks!

I was thinking either two small buttons, or even just plain-text links might be better, centred at the top of the page.

Or maybe one on the left side and the other on the right side, vertically aligned in the centre, perhaps rotated 90 degrees.

Also open to any ideas you have!
