No default initialization of light and emitter in tinygltf::Node

[dyollb]

Describe the issue

No default initialization of light and emitter in tinygltf::Node.
This causes crash in json serialization

To Reproduce

• Windows
• MSVC (Visual Studio 2019), debug build
• This happens also in example: https://github.com/syoyo/tinygltf/blob/release/examples/build-gltf/create_triangle_gltf.cpp

Expected behaviour

Code should initialize parameters not marked as required (or all) with something meaningful that can be tested against, e.g. -1.

Fix:

namespace tinygltf {
class Node {
 public:
  Node() = default;

  DEFAULT_METHODS(Node)

  bool operator==(const Node &) const;

  int camera = -1;  // the index of the camera referenced by this node

  std::string name;
  int skin = -1;
  int mesh = -1;
  int light = -1;  // light source index (KHR_lights_punctual)
  int emitter = -1; // audio emitter index (KHR_audio)
