Add CLI for finetuning Segment Anything

[anwai98]

I think it would be nice to have a simple CLI for finetuning SAM / micro-sam models (and have heard of some requests from other users as well)! What do you think @constantinpape?

PS. I will only come back to this early next month!

Yes, I agree that this would be good to have.

Another feature request: (I've also been thinking about this for a while now)

• It would make sense to not store model checkpoints in the current working directory, and allow users to specify their directory (using save_root). From what I understand, this should be updated! (https://github.com/computational-cell-analytics/micro-sam/blob/master/micro_sam/sam_annotator/training_ui.py#L244-L250)
• Review the advanced parameters:
  • Initial model: we can fetch the value from Configuration and set it to default, or display a template. I've seen users get confused about it!
  • Checkpoint: Is there a reason to put a default value there? I would call it something like Checkpoint path and provide a template for a filepath.
  • Can we support an export script which stores the SAM model state and decoder_state in one filepath? (this would simplify our design to export all relevant components for the finetuned model)
