Rai-Net Access Battlers 0.3.0b

Here's an update of Rai-Net, I updated the project from Unity 2022.3.3f1 to 6000.0.37f1, so I had to do a big update to make everything works back, it basically changes nothing in the game except the network protocol so you can't play with old builds.

This update is still a big uptade because it means that I'll work again on Rai-Net to make it better.

Anyway if you are curious about what changed in the project, you can check the github page and commit 0.3.0b, basically uptated Unity, packages, added some assembly definition and changed file architecture.

That's it :3
