As of now, protobuf maps are represented with [std::collections::HashMap](https://doc.rust-lang.org/stable/std/collections/struct.HashMap.html), which serves as a robust default. In rarer instances, opting for a different implementation, such as BTreeMap, might be desirable, e.g. for deterministic serialization (#496). This change * adds `btreemaps` codegen option to generate [std::collections::BTreeMap](https://doc.rust-lang.org/std/collections/struct.BTreeMap.html) for maps representation.
