improved wandb hyperparameter tracking + tagging

[sfluegel05]

The wandb logger will now log more extensively, including

• data parameters (e.g. batch size, chebi version, split size)
• optionally (if the verbose_hyperparameters flag is set for the logger class): hyperparameters from other classes (e.g. logger, callbacks)
• wandb-tags (can be set a as a hyperparameter in the logger config)

A wandb_logger.yml that uses these features might look like this:

class_path: chebai.loggers.custom.CustomLogger # Extension of Wandb logger
init_args:
  save_dir: logs
  entity: 'chebai'
  project: 'simons_personal_project'
  log_model: 'all'
  verbose_hyperparameters: True
  tags:
    - "run for demonstrating tags"
    - "different tags can be combined"
