Broken dependency on pettingzoo

[Shmuma]

Hi!

Version 0.3.3 depends on pettingzoo >= 1.23.1, but all the versions of pettingzoo above 1.22 are not compatible with MAgent2 environment creation and cause this: #31

To fix, you need to forcefully install the pettingzoo 1.22.3

Hi.

This Problem does still exist.
(Python 3.12.4 via pyenv on a apple sillicon M1)

I tried pettingzoo 1.23.0, 1.23.1 and 1.24.3.
None of them is compatible and I get the following error:

pettingzoo/utils/conversions.py", line 284, in reset
    self._observations, self.infos = self.env.reset(seed=seed, options=options)
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ValueError: too many values to unpack (expected 2)

when I try to execute "env.reset()" in

from magent2.environments import battle_v4

env = battle_v4.env(map_size=16, render_mode='human')

env.reset()

for agent in env.agent_iter():
    observation, reward, termination, truncation, info = env.last()
    action = policy(observation, agent)
    env.step(action)

Would be grateful for help.
