[Feature Requests] Subtract specified amount of time from final time

Nobody has claimed this yet.

With image-based autosplitting becoming more commonly used, myself and others would really like to see a feature which allows you to subtract a certain amount of time once the run ends. Many games do not have a very good frame that can be used to detect when the run ends, but most games have a visual cue that follows slightly later that can be used to end time. For example, the run would end, then 5 seconds later the timer would end. 5 seconds would then be subtracted from the final time.

I honestly do not know if this would be easy to implement or not, but I would absolutely love to see this in the future. For a game I'm currently running, image-based autosplitting works perfectly except for the very end of the run, where I have to manually end time.

Start by tracing how image-based autosplitting detects the end of a run and how the final time is recorded. Determine where a user-specified subtraction would fit, then define expected behavior for the delayed visual cue and verify the resulting final time; the issue names no files or tests to run.
