Pull Request: Add vaast-image Plugin

Summary

This PR adds the vaast-image plugin to the repository. This plugin is meant to be used in a VAAST (Visual Approach and Avoidance by the Self Task) experiment. The plugin displays a single trial with an image stimulus appearing on a background image. Participants respond by pressing a key to approach or avoid the image stimulus, as specified by the instructions. The scene changes accordingly.

Features

• Displays image stimulus on customizable background images
• Configurable feedback for incorrect responses (e.g., training phase)
• Supports background images based on position
• Allows the researcher to force the participant to press the correct key to continue
• Adjustable stimulus size and trial duration
• Collects detailed trial data (stimulus, response, correctness, RT, movement, position)

Additional Notes

A verification of the contribution's functionality may be accomplished by using the example file and the testing file.
A later PR will consist of the addition of a link to a website, created to help researchers use this plugin (and the two other VAAST plugins) to create VAAST experiments.
