cargo update emits an error on yanked version ofwg crate.

$ cargo update
    ...
    Updating crates.io index
error: failed to select a version for the requirement `wg = "^0.3"`
candidate versions found which didn't match: 0.9.1, 0.9.0, 0.8.3, ...
location searched: crates.io index
required by package `stretto v0.7.1`
    ... which satisfies dependency `stretto = "^0.7.1"` of package `mokabench v0.10.0 (... /mokabench)`
perhaps a crate was updated and forgotten to be re-vendored?

stretto v0.7.1 depends on the yanked version v0.3 of wg. We should update stretto to v0.8.x.
