Add og image option

[BramVanBerkel]

Hi! Thank you for your great work on this package. Would it be an option to add the generating of an og image with the dimensions of 1200*630 pixels (the recommended size of an og image)?

Thanks in advance!

Other sites like Reddit use square og:images.

It may be worth investigating how Facebook, Reddit, and Twitter treat multiple og:image tags with different aspect ratios to see what the best to generate are.
