Update to native-lib-loader version 2.0.2

With this commit, we use the latest version of native-lib-loader which includes an upstream NPE fix in `BaseJniExtractor.deleteLeftoverFiles()`.

The initial bug was reported on MATLAB R2013b/Java 1.7.0_11-b21/Win 7/Bio-Formats 5.0.3 where  `bfGetFileExtensions()` resulted in a `NullPointerException` (see https://github.com/scijava/native-lib-loader/issues/3 for the full stack trace). Minimally, the new JAR should be re-tested via MATLAB and/or the command line tools on a couple of platforms.
