Update edge-sdk publish_map to support format_version 2

[IrinaTerebiznik]

Description

This PR updates the Protobuf definitions to include the new Format Version field. Additionally, the robot.py class has been updated to support this new field and assign it a default value of 2 so maps wont get flipped by default

---

Note

Adds formatVersion to map protobuf and updates RobotSession.publish_map to send formatVersion=2 by default; also introduces GpsFixMessage and pose offset fields, with tests updated accordingly.

• Protobuf (inorbit_pb2.py):
  • Add MapMessage.formatVersion (int64).
  • New message: GpsFixMessage (ts, latitude, longitude, altitude, bearing, accuracy flags, accuracy_meters, frame_id).
  • Extend pose messages with offsets: LocationAndPoseMessage.{offset_x, offset_y} and PoseMessageData.{offset_x, offset_y}.
  • Minor generated-code updates (options/encoding).
• Edge SDK (robot.py):
  • RobotMap gains format_version (default 2).
  • publish_map(...) accepts format_version (default 2) and _send_map sets MapMessage.formatVersion.
• Tests:
  • Update map publish assertions to include formatVersion = 2.

Let's take a close look at the protobuf binding types, and discuss the default value for formatVersion, given that it has the potential of being a breaking change.
