Missing pydot dependency

[milancermak]

I cloned the repo and pip install -e . the package. When I tried to use the -png cmdline arg, I got the following error:

amarna contracts/settling_game/S06_Combat.cairo -png
Traceback (most recent call last):
  File "/Users/m/.pyenv/versions/starkware/bin/amarna", line 33, in <module>

ModuleNotFoundError: No module named 'pydot'

pip install pydot solved it

Hey @milancermak, thanks for reporting this! I've added pydot as a dependency and it should now work when you first install it.
