decode outlook safelinks protection #6
Description
Similar to #5, Outlook will rewrite URLs with *[.]safelinks[.]protection[.]outlook[.]com, so at some point you get an abomination of multiple entities rewriting each others' URLs.
We should find and unwrap these, to a certain limit.
(At some point, a URL could be rewritten so many times that it takes up more space/bandwidth/processing than the original email itself.)
