27b0f7ca0d Overhauled the tracker system (#172)
* Overhauled the tracker system
Separated the logging and saving capabilities
Changed creation to be consistent and initializing behavior to be defined by a class initializer instead of in the training script
Added class separation between different types of loaders and savers to make the system more verbose

* Changed the saver system to only save the checkpoint once

* Added better error handling for saving checkpoints

* Fixed an error where wandb would error when passed arbitrary kwargs

* Fixed variable naming issues for improved saver
Added more logging during long pauses

* Fixed which methods need to be dummy to immediatly return
Added the ability to set whether you find unused parameters

* Added more logging for when a wandb loader fails
