Fixed eslint warnings Fixing tests that failed Added unit tests for ARD authentication Fixed an issue with the ARD rfb version number in the unit tests Fixed issue with username/password lengths Username and password lengths are now capped at 63 characters each. Improved code for sign bit on public key bytes. UTF Encoder username and password before packing it Change UTF encoding to encode the username and password before packing it to prevent it from being expanded beyond the allowed size. Public key is truncated to proper key length. Replaced forge with web crypto for ARD authentication Changed the way in which the async methods are handled, added unit tests to verify ARD encryption output. Update .eslintignore
