protogen(BREAKING)!: support multiple union type definitions in a sheet

[wenchy]

• close protogen: support multiple union type definitions in a sheet #174

❗BREAKING CHANGE

In file proto/tableau/protobuf/tableau.proto, we changed the union option type from bool to UnionOptions for more better extensibility and design consistency.

Old：

extend google.protobuf.MessageOptions {
  WorksheetOptions worksheet = 50000;
  bool union = 50001;
}

New:

extend google.protobuf.MessageOptions {
  WorksheetOptions worksheet = 50000;
  StructOptions struct = 50001;
  UnionOptions union = 50002;
}

message StructOptions {
  string name = 1;  // Worksheet name.
  string note = 2;  // Struct type note. Maybe in another language (Chinese).
}

message UnionOptions {
  string name = 1;   // Worksheet name.
  string note = 2;   // Oneof note, maybe in another language (Chinese).
}

Compatibility resolution

• If union type is defined in a sheet, please regenerate all union types.
• If union type is defined in proto file, then change the union option from bool to UnionOptions. For example:
