volctl 3.0.0

Breaking changes

The non-native part of the library has been reimplemented in Java. This removes the dependency on the Kotlin standard library, but it also breaks Kotlin constructor calls using named arguments. Otherwise everything should be source-compatible.

Other:

• Removed static VolumeControl.isWindows() function

Bugfixes

• COM objects are properly closed (#4)
• Windows getVolumeNative() implementation is rounding properly (#7)
• Relative library dir paths are now supported (#6)
• The classloader-level initLock was replaced by locking library file
