And other refactorings and fixes

And other refactorings

I can't test it yet because the API is full of errors because of the refactoring

- Created a new Client class
- Made more use of runtime compiled lambdas, not sure if it's a good idea but anyways
- Removed constructor overload for ECS object base, anything other than getting by EGID should be a method
- Started work on automatically getting information about ECS entities

- Fixed compilation errors
- Fixed patching errors and added missing anti-cheat patch
- Added check to verify that the init data has been removed from blocks once they are placed in game
- Removed block place event deduplication as it seems to be not needed anymore
- Fixed async tests not properly running
- Added Player.State
- Attempted to fix seat entering/leaving (we can only send inputs in client code)
- Fixed the weak dictionary ContainsKey returning true even if the item is no longer there

- Fixed the time mode toggle not working during testing (changed the runner)
- Made the testing thing wait until the time toggle finishes
- Fixed the Game.Enter/Exit event being triggered on time mode change
- Added a way to spawn and despawn the player's machine (which doesn't work yet)
- Fixed the Player.Id property always being 0
- Attempted to fix the fake action inputs not working in simulation

- Added support for seat enter and exit events and a test for them
- Added support for entering and exiting seat from code
- Changed the Id property of ECS objects to non-abstract, requiring it in the constructor, so that the Player class can inherit EcsObjectBase
- Added a weird constructor to EcsObjectBase that allows running code to determine the object Id
- Added interface for engines that receive entity functions
- Exposed the entity submission scheduler and removed it from FullGameFields because it moved from there
- Made the Game.Enter event only fire after the first entity submission so the game is fully initialized and the local player exists
- Added all seat groups to the dictionary

- Added a wrapper class that handles the individual wrapping of event handlers to individually handle exceptions - now it tracks the wrapped event handlers so it can unregister them properly
- Fixed an exception that happened when two ECS objects were created with the same EGID
- Added support for returning an existing ECS object if it exists instead of always creating a new one
- Added a parameter to the entity query extension methods to override the group of the ECS object (could be used for the player properties)

ECS objects are stored in a newly created weak dictionary so that events can be called on them and possibly other things can be done with them

Added extension methods to query data from ECS objects
Added base class for ECS objects
Added support for representing in-construction ECS objects with an OptionalRef<T>

Added some TODOs as well

Newly created blocks use the initializer to set properties, allowing the user to set per-block properties
