Integrations with oysteR #210

Thanks @csgillespie for reaching out at useR! - This looks like a really cool package to integrate with.

oysteR looks like an awesome resource for identifying security vulnerabilities in packages. From a brief readthrough, it looks like it compares a package against the Sonatype OSS Index, identifying known vulnerabilities.

Please refer to #209 to help consider how package integrations should be managed
