CS2: Player Inventory now includes initial loadout at the beginning of the game

[esbengc]

Fixed an issue in CS2 where Player.Inventory would not include any weapons with which the player started.

As a simple test run the following program (for my own test, I used https://www.hltv.org/matches/2367165/rhyno-vs-perroflautas-aveiro-techdays-cup-2023 map 2 anubis):

func main() {
	demoFilePath := flag.String("demo", "", "path to demo file")
	flag.Parse()

	demoFile, err := os.Open(*demoFilePath)
	if err != nil {
		panic(err)
	}

	parser := demoinfocs.NewParser(demoFile)
	if err != nil {
		panic(err)
	}

	parser.RegisterEventHandler(func(_ events.RoundStart) {
		fmt.Printf("Round start: %d\n", parser.GameState().TotalRoundsPlayed()+1)
		var players []*common.Player
		players = append(players, parser.GameState().TeamTerrorists().Members()...)
		players = append(players, parser.GameState().TeamCounterTerrorists().Members()...)
		for _, player := range players {
			fmt.Print(player.Name, "has the following weapons:")
			for _, weapon := range player.Weapons() {
				fmt.Print(" " + weapon.String())
			}
			fmt.Println()
		}
		fmt.Println()
	})

	err = parser.ParseToEnd()
	if err != nil {
		panic(err)
	}
}

For round 1, it will print completely empty inventories for everybody. For round 2, it will not include any weapons that any surviving players had through the entire round 1.
