Move syn() convenience method from InputDevice to EventIO

[Lawstorant]

This one mimicks the syn() method found in UInput class and just makes it easier to inject EV_SYNC events. It's easier to parse event blocks visually.

Thanks. Maybe the syn method could be moved to the EventIO BaseClass, from which both InputEvent and UInput inherit

[Lawstorant]

I actually thought about that! I wasn't sure if that would work though as UInput works a bit differently and doesn't reference self. In the end, it would work the same, as the method would be just overridden, but at that point, does it make sense to inherit it just to override?

If yes, I'll update the PR

[sezanzeb]

I think it would, because the self.write method you are using right now also calls EventIO.write through inheritance, doesn't it? I think there is no need to overwrite anything.

[Lawstorant]

Okay, I went through the paths and you're right. EventIO uses the same path to perform write() as the syn() method in UInput. I'll just move syn to the EventIO.

One more question, what do you think about syn() using self.write() instead of _uinput.wirte() directly? I think that's a fair abstraction. If anything ever needs to change about the write operation, it has to be done only in one place.

Yes, I agree

Is this ready to be merged?

[Lawstorant]

As far as I'm concerned, yes.
