* feat: adding the ability to encrypt/decrypt data based on the biometric auth
Adding the method biometricCipher() that allows to use the biometric authentication to use a generated key from android that can be accessed only through the biometric authentication. The method uses this key to encrypt/decrypt the data provided by the caller in the "options" parameter, with "dataToEncrypt" or "dataToDecrypt" filled.
Changes were done both on Kotlin, Rust and JS sides.
* Improving the way we encrypt data by allowing only if the biometric was successful.
* Adding a warning on the JS side
* Adding doc changes in readme.md
* Adding doc changes in readme.md
* Update README.md - it was updated incomplete
