Delivering liboqs-java as a JCE provider

[pruthig]

Hi Team,
Can we refactor the code and make changes so that liboqs-java can be used as JCE provider? It means, for instance, creating a subclass of SignatureSpi and invoke wrapper functions from the member functions of that subclass. It will help a lot of people who want to pick it as a plug-and-play artifact based on JCE provider framework.

Sounds like a sensible enhancement @pruthig . Would you be willing to keep maintaining this going forward? You may have seen that this language wrapper is one of our least well "looked after" sub projects.....
