Single-Shot Localizer-Detector for site testing

In this release, we created and trained a single-shot localizer-detector algorithm to address the lighting (sun, over-exposure) issues that we faced in previous submissions.
All changes only apply to the test site environment. No changes for the simulator environment.
The simulator still relies on a 2-step approach: localization and detection. The site will use the single-shot algorithm which combined localization and detection.
