* A mapper between IANA time zone identifiers and BCP-47 time zone identifiers.
*
* This mapper supports two-way mapping, but it is optimized for the case of IANA to BCP-47.
* It also supports normalizing and canonicalizing the IANA strings.
*
* See the [Rust documentation for `IanaParser`](https://docs.rs/icu/latest/icu/time/zone/iana/struct.IanaParser.html) for more information.
