Somehow, if we don't close the classloader used to read .tasty files from jars, a subsequent compilation run might end up reading a stale version of the .tasty file which does not exist on disk anymore. I don't understand why this happens since we don't reuse the classloader itself, but that's life sometimes ¯\_(ツ)_/¯

The previous commit tried to fix some weird caching behaviors by closing the classloader used to read a .tasty file, but it turns out the JVM is dumb and that breaks any other in-use classloader that uses the same jar. Give up on the whole thing and work directly with the underlying ZipArchive to find the .tasty file (this just required adding a "parent" field to ZipArchive#Entry).
