Please impl Default for mos6502::cpu::CPU

[omarandlorraine]

I'm rejigging my project to use use emulator but I'm running into this issue where the Default trait is not impl'd for mos6502::cpu::CPU.

I wanted to do this

impl Default for mos6502::cpu::CPU {
    fn default() -> Self {
        Self::new()
    }  
}

but it's not allowed because neither Default nor mos6502::cpu::CPU are from my crate

That said I don't really know what Default::default should do here. On the real chip, some of the registers are not preset to a value at reset.

What do we think?

We discussed that in #50 (comment). Would that work for you?

Oh yikes! I completely forgot about that. Apologies for the noise
