Microsoft Automation

While the pages for various MS pages are easy enough to parse, (See https://learn.microsoft.com/en-us/officeupdates/sharepoint-updates for eg) - a common problem was with the dates not being accurate enough.

I'd raised this https://github.com/MicrosoftDocs/OfficeDocs-OfficeUpdates/issues/363, but dates are KB specific, and not mentioned on the main page. It's unlikely this will change.

As a workaround, I've created a KB-date mapping here: https://github.com/captn3m0/microsoft-kb-metadata, so we can use that instead.
