Using a hardcoded signature ensures that the libraries cannot be swapped out without a core auto update, which requires the standard dev team approval process.
Note: this relies on (a modified version of) liblitewallet-jni which is not included, but will ultimately be compiled for each supported architecture and hosted on QDN.
LiteWalletJni code is based on https://github.com/PirateNetwork/cordova-plugin-litewallet - thanks to @CryptoForge for the help in getting this up and running.
