/** 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 `TimeZoneIdMapper`](https://docs.rs/icu/latest/icu/timezone/struct.TimeZoneIdMapper.html) for more information.
