Google Authenticator for Android v5.00

Snapshot release of Google Authenticator v5.00.

This version of Google Authenticator now matches the version found on the Play Store, save for certain experimental features (e.g. security key support) and any usage of internal/proprietary Google tools. Since the last major open source release from Google was ~7 years ago, the diff for this release is rather large.

Please note that the open source version of Authenticator is not an officially supported Google product, and there are no guarantees that this repository will continue receiving upstream changes (or vice versa).
