## Issue Addressed
Automates a build and push to antithesis servers on merges to unstable. They run tests against lighthouse daily and have requested more frequent pushes. Currently we are just manually pushing stable images when we have a new release.
## Proposed Changes
- Add a `Dockerfile.libvoidstar`
- Add the `libvoidstar.so` binary
- Add a new workflow to autmatically build and push on merges to unstable
## Additional Info
Requires adding the following secrets
-`ANTITHESIS_USERNAME`
-`ANTITHESIS_PASSWORD`
-`ANTITHESIS_REPOSITORY`
-`ANTITHESIS_SERVER`
