Ensure that library only uses system libsodium library

[tomwetjens]

As a Shapeshifter Library User

I want the open source library to use the system-only library

So I have a guarantee that I am using the correct version of the libsodium library

Our Java open-source library uses the lazysodium-java wrapper library, and we have complete control over that because it is part of our pom.xml. However, the lazysodium-java library calls the native (C) library libsodium to do cryptographic actions like signing and verifying our UFTP flex messages. We want to make sure we are using the most recent version of the libsodium library, with the most recent fixes.

Hint:
You can specify in the constructor of LazySodium how you want to load the shared library
