Add `ResourceUtils` and `createEphemeral*`
We have identified helpers that are used in multiple places:
nl.rug.digitallab.themis.assignments.util.ResourceUtils
-
nl.rug.digitallab.common.quarkus.archiver.createEphemeralDirectory
andnl.rug.digitallab.common.quarkus.archiver.createEphemeralFile
We should make these a Common Kotlin Library
