microsoft-office365 contains CIDR blocs

[Rafiot]

List of known Office 365 URLs and IP address ranges contains some CIRD blocks, but as it is a mix of domains, IPs and blocks, it is quite difficult to properly figure out what is in this list.

And as the type isn't cird, I'm pretty sure MISP doesn't use this list properly.

@iglocska what do you think?

I can split the list of microsoft-office365 into different warning-lists per type cidr, string and hostname. But it would be cleaner to maintain a single list and being able to support the type depending of the format within the warning-list.
