Add function to create app

[roomrys]

Description

When testing things, I often find myself running subsets of sleep.gui.app.main. This PR just breaks up main a little bit and adds a create_app function. Mainly for troubleshooting/testing.

sleap/gui/app.py (5)

• 264-267: The dropEvent method has not been changed in this hunk. It appears to be identical to the old hunk.

• 1604-1612: The function create_parser has been renamed to create_sleap_label_parser for clarity. This is a good practice as it makes the function's purpose more explicit. Ensure all calls to this function have been updated to reflect the new name.

• 1652-1659: The creation of the Qt application, which was previously done in the main function, has been moved to a new function create_app. This improves modularity and makes the main function cleaner. Ensure all necessary initializations for the Qt application are done in this function.

• 1662-1668: The main function now uses the renamed create_sleap_label_parser function and the new create_app function. The labels argument has been removed from the function signature, simplifying its usage. Ensure that all calls to this function have been updated to match the new signature.

• 1677-1680: The main function now uses the create_app function to create the Qt application. This makes the main function cleaner and more readable.
