Entities transmit alternative.

[CookStar]

This draft is derived from #332 & #332 (comment) & 14a38d4

Currently, there are ongoing discussions on how to implement the feature.
I've made a pull request as a draft for code review.

Example:

#Hide the teammates from each other.
@Event("player_spawn")
def on_player_spawn(game_event):
    player = Player.from_userid(game_event["userid"])
    for other in PlayerIter():
        if player.team_index == other.team_index:
            player.hide_entity(other.index)
            other.hide_entity(player.index)

#An optional reset, for spectating the game.
@Event("player_death")
def on_player_death(game_event):
    player = Player.from_userid(game_event["userid"])
    for other in PlayerIter():
        player.reset_entity(other.index)

Here's my opinion on the Entities transmit (hidden/shown state) feature. #332 (comment)

[ArtichaTM]

Hmm, something wrong

from _entities._transmit import transmit_manager

@ClientCommand('test')
def test(_, index):
    player = Player(index)
    print(transmit_manager.get_hidden_entity(player.index))

gives me:

1

I found the reason. I don't why, but when I hide weapon_c4 from Terrorist (me, tried alone and with bots — all the same), suddenly he can't find this c4. Idk why xD

He can't find c4 when:
CT — when c4 on floor
T — nevermind, even if bomb in player

That's so weird. After several round restarts, bomb entity changed, but he show in tuple previous entity, and new (if I add to no_transmit). But If I hide new bomb and restarts round, everything going the same
