The support for multi-agent in ProcTHOR-10k.

Can the scene in procthor-10k support multi-agent setting?
When we load the ai2thor scene, and use agentCount=2 to initize two agents, we can get the following event results of `c.last_event.events`:
```
[, ]
```
But when we load the procthor-10k scene, and use agentCount=2 to initize two agents, we can only get the following event results of `c.last_event.events`:
```
[]
```
We use the controller by
```
house=dataset["train"][0]
c = Controller(scene=house, agentCount=2)
```
And when we try to make the agent of agentId=1 to execute the specific action by `e2 = c.step("RotateRight", agentId=1)`, it would get this error:
```
Traceback (most recent call last):
File "../lib/python3.9/site-packages/ai2thor/controller.py", line 979, in step

raise TimeoutError(f"Reading from AI2-THOR backend timed out (using {time out}s) timeout.")
TimeoutError: Reading from AI2-THOR backend timed out (using 100.0s) timeout.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "", line 1, in

raise (TimeoutError if isinstance(e, TimeoutError) else RuntimeError)(

```
So how to use the multi-agent setting in the scene of Procthor-10k?
