Allow retracking of old predictions

[getzze]

Software versions: SLEAP: 1.2.8

Description

PR #898 allows to retrack predictions, but for using with the GUI, it would be nice to have the option to define a prediction file to retrack. This PR adds options to the GUI for that. It also makes retrack work with the GUI, it's currently broken.

It could be done better if the option was added in the predict_on combo_list at the bottom of the inference window, but it was a bit too complicated to understand how this widget is populated... This is work in progress.

Hi @roomrys, So, it's working but I'm not very satisfied with it, but I don't know how to improve it. So it would be nice if I can get some feedback from you :) Thanks!
