jna dependency is out of date

[spiralmike]

This package is built to require jna and jna-platform version 4.1.0 via a versioned jar reference in the manifest CLASSPATH.

The latest version of these packages is 5.8.0, and other libraries in my project do not work with the older version.

Working around it by copying the 5.8.0 jars to filenames with the 4.1.0 version number seems to work fine- i.e. sass-java appears to work with jna 5.8.0 without modification.

Would it be possible to release a newer version of this library that uses jna 5.8.0 and perhaps does not hard-code the specific version into the manifest?
