Update icu_locid, icu_properties (#91)

This update brings us to zerovec 0.10.4 which addresses a flaw that
Dependabot is warning about:

> The affected versions make unsafe memory accesses under the
> assumption that `#[repr(packed)]` has a guaranteed field order.
>
> The Rust specification does not guarantee this, and
> rust-lang/rust#125360 (1.80.0-beta) starts reordering
> fields of `#[repr(packed)]` structs, leading to illegal memory
> accesses.
>
> The patched versions 0.9.7 and 0.10.3 use `#[repr(C, packed)]`,
> which guarantees field order.
