ShadowCopyAction isn't closing input streams

Please check the User Guide before submitting "how do I do 'x'?" questions!

Shadow Version

2.0.2

Gradle Version

4.5

Expected Behavior

Everyplace the code is calling archive.getInputStream or otherwise opening a stream should be closed. For example, copyArchiveEntry should close the inputStream from archive.getInputStream as IOUtils.copyLarge does not.

Actual Behavior

Our build process runs out of file handles while building our shadow jars.
