Add game modes similar to AAS & RAAS

If you don't know what AAS & RAAS are, you can check out these two links:

I think the AAS & RAAS modes effectively address the issue in Conquest mode where the game becomes a revolving door of teams capturing points in turn.

Coupled with the current map design similar to squad, most control points do not offer sufficient defensive advantages to the side closer to them.

The sequential capture nature of AAS & RAAS requires both sides to consider both offense and defense, which may be more suitable for the current state of the game.

Played both in Squad, we implemented AAS to BattleBit in back 2020, it was a cluster f*ck, majority didn't know how it played and reported as a bug when they couldn't capture a flag without capturing the previous ones.

And we did alot to add on UI, make it obvious which flag to capture, on map and game HUD both, YET, players just kept going with their instincts, which is the middle of the map, and attempt to capture whatever there is

Despite I like both of those gamemodes, specially AAS, they do not work on arcade player base, majority doesn't pay any attention how those gamemodes even played.
