JNA-4.4.0 shipped in MC 1.12.2 (possibly earlier too) conflicts with JNA-3.4.0 dependency

Minecraft now uses the JNA-4.4.0 implementation. This causes a possible incompatiblity with the native part of the MumbleLink mod or LinkAPI

This might warrant a switch back to the original non "QnD" branch. In any case the compatibility with the JNA shipped with Minecraft needs to be investigated.

Issue #11 was used to revert the dependency from JNA-4.0.0 to JNA-3.4.0 maybe this only needs to be reverted to fix the problem.
