Use of unstable library feature

[KeironO]

Hey there,

The following lines in lib.rs feature an unstable feature (copied).

let std_flag = tz.standard_flags.get(i).copied().unwrap_or_default() != 
let gmt_flag = tz.gmt_flags.get(i).copied().unwrap_or_default() != 0;

https://github.com/rust-datetime/zoneinfo-compiled/blob/master/src/lib.rs#L131-L132

Error thrown:
