[jdeschamps]

Description

If CAREamics is used in a multithreaded application (e.g. napari plugin), then we need a way to stop the training programmatically. This PR add a stop_training method to the CAREamist.

Additionally, this PR removes the unused parameter experiment_name from the CAREamist.

• What: Add stop training method.
• Why: Enable stopping training in multithreaded applications (e.g. napari)
• How: Add stop_training method that raises the should_stop flag of Lightning.

Changes Made

• Modified: careamist.py, by adding the stop_training function and cleaning up unused keywords.

Can’t take a proper look rn but the last paragraph of the docstring in CAREamist.__init__ mentions the experiment name so I guess this should also be removed.

Fixes #195
