Shall the objdump API be included in libwabtjs target

[JesseCodeBones]

currently the target libwabtjs will export APIs:

  validate(): void;
  resolveNames(): void;
  generateNames(): void;
  applyNames(): void;
  toText(options: ToTextOptions): string;
  toBinary(options: ToBinaryOptions): ToBinaryResult;
  destroy(): void;

is it possible to export the objdump API for the JS side, so if user want to get the objdump info, they do not need to start up a process? I suppose the objDump() just return the text will be good, how do you think? Thank you.
