[feature] Comparison

[opastorello]

Describe your idea

I would like the possibility of comparing two apk, for example, one original and one modified, for example, and understand where any changes were made.

Implementing a good comparison would take a lot of work considering that file/content comparison is not used elsewhere in Jadx-Gui.

In my opinion you should better use the Save all function of Jadx-Gui on both APK files to be compared and then use a file comparison tool of your choice to compare both saved folders with resources and sources.
