Nebula API

NebulaModAPI

• Add event Action<int> OnDysonSphereLoadFinished, which invokes after dyson sphere loading is completed on client.
• Change OnPlayerJoinedGame trigger time, now it invokes when the player synced all the data.
• Change OnPlayerLeftGame trigger time, now it invokes when the synced player disconnected.

INetworkProvider

• Add SendPacketExclude<T>(T packet, INebulaConnection exclude)

IPlayerManager

• Add INebulaPlayer GetPlayerById(ushort playerId), which check player from all source (connected, syncing, pending)
• Add SendPacketToOtherPlayers<T>(T packet, INebulaConnection exclude)
• Remove SendTechRefundPackagesToClients(int techId)

INebulaPlayer

• Remove int CurrentResearchId, long TechProgressContributed

INebulaConnection

• Add IEquatable interface, now it can use .Equals(INebulaConnection other) to test value equality.
• Add SendRawPacket(byte[] rawData)

IPlayerData

• Remove Float4[] MechaColors

Nebula Mod

• Remove MechaColors because it's now replaced by MechaAppearance
• Remove tech contributed and refund code in NebulaPlayer.
• Remove NebulaNetwork.StorageSyncManager and use SendPacketToStar instead.
• Refactor joining process, now when the client successfully joins, the host will call SimulatedWorld.OnPlayerJoinedGame. When a connected client leaves, the host will call SimulatedWorld.OnPlayerLeftGame
• Remove empty lines and hash strings in copied error message

You should bump NebulaAPI's version and changelog with this PR.

I guess version should be 1.3.0
