feat: Parse IANA timezones in an InfluxQL TZ clause (#6585)
* feat: Parse IANA timezone strings to chrono_tz::Tz * feat: Visitors can customise the return error type This avoids having to remap errors from `&'static str` to the caller's error type, and will be used in a future PR for time range expressions. * chore: Run cargo hakari tasks Co-authored-by: CircleCI[bot] <circleci@influxdata.com>pull/24376/head
