WIP: Updating Yolo

[FlowSs]

Here, we will update YOLO with the new classes we discussed about to match the decision node, thus:

0 red_armor
1 blue_armor
2 grey_armor
3 base
4 std (standard)
5 hro (hero)

We might add a 6th class for "default", although it does not seem needed for now. In particular, we have no data on the new sentry, so we can not really integrate it as a class now. We might need to add it after whenever we have a armor module with the sentry's symbol (since the sentry will look similar in design to a standard).
