update to Rust Edition 2021

this does not involve any code changes, it just sets the new edition, allowing to use newer features in the future. as the crate is anyway only compiling with a recent nightly compiler there's no problem with requiring edition 2021 (it was first introduced in Rust 1.56). note that running `cargo fix --edition` (as suggested by the [migration guide]) isn't possible as workspace-level cargo commands fail in this repository due to the feature flags :( the resolver has been specified in the workspace due to the following build warning being issued if it's not present: > warning: some crates are on edition 2021 which defaults to `resolver = "2"`, but virtual workspaces default to `resolver = "1"` > note: to keep the current resolver, specify `workspace.resolver = "1"` in the workspace root's manifest > note: to use the edition 2021 resolver, specify `workspace.resolver = "2"` in the workspace root's manifest [migration guide]: https://doc.rust-lang.org/edition-guide/editions/transitioning-an-existing-project-to-a-new-edition.html
