- Updates deps
- Some README updates considering the Winit backend based on
android-activity has been merged upstream
- runs cargo fmt over examples
- Top-level Cargo.toml simply excludes "examples" instead of
listing each sub-directory separately
The winit based examples no longer have an explicit dependency on
android-activity and they instead consume the `android-activity` API via
the Winit crate so there's no need to keep the versions synchronized.
