Add more commands

[Anonymous4045]

This tool is great for automating some of the process of playing through everyone's games. However, I believe it should go a bit further.

One hassle I have each PyWeek is setting up each game to run correctly. There's all these conventions and suggestions, such as having a requirements.txt and a run_game.py, but these are often overlooked or incorrectly implemented by the developer. It would be very nice if we had a standard way to check that a zip file is correctly formed. I think a "verify" command for this tool can do just that.

Additionally, I'd like to propose that this tool has the functionality to also extract, and try to run, each entry. If all (realistically not all, but hopefully some) developers make sure their games are in the correct format with the verify command, the people who play the games should be able to run it with simply "pyweek play (entrant name)". Then the tool can extract the game, set up the venv, install the requirements, show the readme, and run the game.

I believe I can implement all of these features if this is approved.

Participants are developers and as such would be happy to make their game run out of the box.
If the cli could work on local files and testing this way would be suggested on the main page, I doubt there would be many entries failing to do so. This should not be enforced though, it would just be nice.
