adds the ability to put your pet to sleep and wake them up again

[danieldelcore]

Super basic implementation for sleep/wake interactions.
Adds two quick commands to control their sleep and placeholder animation config.

Right now, the sleep state is equivalent to idle in that the pet will just remain idle until you manually wake it up again.

Ultimately would be interesting if we could tie this into the progression system somehow.
I.e. You have to keep your pet well-rested in order to progress with their experience and have them evolve.

ps really love the art you've created for this project, really excellent work!
pps No pressure to accept this PR if it doesn't align with your long-term vision 😄.

This is awesome! I haven't tested, but the code looks good to me.

I would like to wait to merge this one with some sleep animations for each character 💤

I can't take any credit for the art - I was working with an awesome pixel artist who has gone AWOL unfortunately 😔 BUT I'm working to find more skilled pixel artists for animations and backgrounds.

No worries at all! I assumed it would be best to hold off until there were some proper sleep animations! That sounds good :)

That's a real shame about the artist! Hopefully you can find someone to take over soon!
