Because this function manipulates the import system in a way that might
be fragile or do unexpected things if it is run many times, it uses a
`call_once` decorator to ensure that this is only ever called exactly
one time — in other words, when using this function you will only ever
get one copy of each module rather than a fresh import each time.

This is necessary because `pickle` will refuse to serialize
an type calling itself `zoneinfo.ZoneInfo` unless `zoneinfo.ZoneInfo`
refers to the same object.
