Subject: [PATCH] Add a MSRV CI job (#1094)

* Add a MSVR CI job

Check that we don't use features that are only available on newer Rust versions.

* Add `rust-version` field to node hub packages

* Exclude `dora-rav1e` in `msrv` test job

* Add a name for the msrv job

* Exclude `dora-dav1d` in `msrv` test job
