Registers a zone rules provider.
This adds a new provider to those currently available.
A provider supplies rules for one or more zone IDs.
A provider cannot be registered if it supplies a zone ID that has already been
registered. See the notes on time-zone IDs in ZoneId, especially
the section on using the concept of a "group" to make IDs unique.
To ensure the integrity of time-zones already created, there is no way to deregister providers.
