[Pkg-rust-maintainers] Bug#1043449: Bug#1043449: rust-tera: Please provide feature date-locale

> Please provide feature date-locale.

The date-locale feature in tera depends on the "unstable-locales" feature in chrono.

There are a couple of issues I see here.

1. It's an unstable feature, it's not clear how much of a maintinance burden that will be going forward.
2. It requires the "pure-rust-locales" crate which is not currently in Debian.
