Function impl_replace_time_zone_fast

pub fn impl_replace_time_zone_fast(
    datetime: &Logical<DatetimeType, Int64Type>,
    ambiguous: Option<&str>,
    timestamp_to_datetime: fn(_: i64) -> NaiveDateTime,
    datetime_to_timestamp: fn(_: NaiveDateTime) -> i64,
    from_tz: &Tz,
    to_tz: &Tz,
) -> Result<ChunkedArray<Int64Type>, PolarsError>

Available on crate feature polars-ops only.

If ambiguous is length-1 and not equal to “null”, we can take a slightly faster path.
