Updated project generator script to always order assemblies (it didn't do that for me on Linux) and to fix minor issues

- Updated project to use .NET Standard 2.1, which is what the game uses
- Updated CodeGenerator to use .NET 6

Neither of them work actually
Added some delay between tests

- 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

A bunch of errors still

It doesn't work but anyway
Also remove parameter that allowed placing blocks in sim

Save game details were changed, they may not work properly
Game mode change event no longer sends game data, needs fixing

Removed old dependencies, including uREPL
Added new block IDs
Implemented basic command handling to support existing mod commands

Added check for time mode toggle to avoid crashing the game
Added support for having the ref folder outside the solution in gen_csproj.py
Removed BlockIdentifiers class
Added check for invalid player ID when placing blocks
Resolved compilation errors

Using QueryEntityOptional directly with the player properties
Character structs are camera structs in build mode
The FlyCam rotation is not updated in build mode, only the camera is

Copying to Plugins folder on build
Registering deterministic game engines automatically
Each event handler is wrapped so if one fails it will still trigger the rest

Except those that actually refer to the game's code

Added some TODOs as well

- Fixed the crash on second time start
- Tweaked more stuff about the block

Breaking changes coming from FMOD 2.0:
- Audio[int index] changed to Audio[PARAMETER_ID index]
- Audio.Parameters removed

Fixed getting the selected blueprint
Fixed block groups not being assigned to first block

Added Cluster.GetSimBodies() and SimBody.GetBlocks()
Fixed some issues with IDs and bad handling of them

Removed BlockIdentifiers.OWNED_BLOCKS as the original got replaced with an array
Added the correct group for each supported functional block
Removed EntityFactory property from IEntitySerializer as it is provided on deserialization

Removed some inputs from FakeInput
