fixes https://luceeserver.atlassian.net/browse/LDEV-652

[andrew-dixon]

Updating metadata-extractor.jar to latest release, 2.8.1, and adding in xmpcore.jar, release 5.1.2, as it is a dependency of 2.8.1. This fixing the issue, it was failing silently due to xmpcore.jar being missing.

normally we do not update jars, because this makes more harm than good as you could see with the http jar update. this rule no longer apply for Lucee 5 where the core manages the jars. We can add this jars but we also need to communicate this update in the community. in addition we should add the ame jars with Lucee 5 i assume, in that case they have to be OSGi bundles of course.

metadata extractor is already part of Lucee 4.5 and 5 see: https://github.com/lucee/Lucee4/tree/master/lucee-java/libs

@micstriit - Yes but as per my original message on this pull request the xmpcore.jar, which is a dependency, is missing causing some files to error silently.
