Need a flexible method to record training data in TensorBoard

• I have marked all applicable categories:
  • exception-raising bug
  • RL algorithm bug
  • documentation request (i.e. "X is missing from the documentation.")
  • new feature request
• I have visited the source website
• I have searched through the issue tracker for duplicates
• I have mentioned version numbers, operating system and environment, where applicable:

  import tianshou, gymnasium as gym, torch, numpy, sys
  print(tianshou.__version__, gym.__version__, torch.__version__, numpy.__version__, sys.version, sys.platform)
  0.5.0 0.26.3 1.12.1 1.21.5 3.7.13 (default, Oct 18 2022, 18:57:03) 
  [GCC 11.2.0] linux
  

Hello, Thanks for your brilliant work! While working with Tianshou, I encountered an issue related to recording training data in TensorBoard. Specifically, I need to record a value from the info dictionary, let's say info["key"], which is similar to an accumulated reward at the end of each episode.
