* Packaging changes:
- `mitmproxy-rs` does not depend on a protobuf compiler being available anymore,
we're now also providing a working source distribution for all platforms.
- On macOS, `mitmproxy-rs` now depends on `mitmproxy-macos`. We only provide binary wheels for this package because
it contains a code-signed system extension. Building from source requires a valid Apple Developer Id, see CI for
details.
- On Windows, `mitmproxy-rs` now depends on `mitmproxy-windows`. We only provide binary wheels for this package to
simplify our deployment process, see CI for how to build from source.
