Improved upsampler training ( #181 )
...
Sampling is now possible without the first decoder unet
Non-training unets are deleted in the decoder trainer since they are never used and it is harder merge the models is they have keys in this state dict
Fixed a mistake where clip was not re-added after saving

Quality of life improvements for tracker savers ( #210 )
...
The default save location is now none so if keys are not specified the
corresponding checkpoint type is not saved.
Models and checkpoints are now both saved with version number and the
config used to create them in order to simplify loading.
Documentation was fixed to be in line with current usage.
