For each protobuf message roto generates three types:

- **Builder struct** `MessageNameBuilder<'b>` — writes into a caller-provided `&mut [u8]`.

- **Builder struct** `MessageNameBuilder<'b>` — writes into a caller-provided `&mut [u8]` or `BufMut`.
|

- **Owned struct** `OwnedMessageName` — owns the byte buffer and implements `RotoOwned`, providing a bridge to the `Reader`.

- **Reserved Fields**: `reserved` statements are ignored.

- **Services**: `service` and `rpc` definitions are ignored.

- **Options**: Field and message options are ignored.

### Tasks
|
||||
|
||||
- [x] Analyze `roto/codegen` to determine which protobuf constructs are supported during code generation.
|
||||
- [x] Analyze `roto/runtime` to determine which wire types and protobuf types are supported during reading and writing.
|
||||
- [x] Compare findings with the Proto3 spec (https://protobuf.dev/reference/protobuf/proto3-spec/).
|
||||
- [x] Document supported and unsupported features in the README.
