Returns a lookup from canonical time zone ID (e.g. "Europe/London") to a group of aliases for that time zone
(e.g. {"Europe/Belfast", "Europe/Guernsey", "Europe/Jersey", "Europe/Isle_of_Man", "GB", "GB-Eire"}).


A lookup from canonical ID to the aliases of that ID.

The group of values for a key never contains the canonical ID, only aliases. Any time zone
ID which is itself an alias or has no aliases linking to it will not be present in the lookup.
The aliases within a group are returned in alphabetical (ordinal) order.
