Macro delays are incorrect

[pixeltris]

As mentioned in #23 macro delays seem to be a bit off. It looks like half the duration you specify, with some sort of dampener as well (like 0.5 seconds additionally off for both 5 second delay and 10 second delay).

If I remember correctly the official software just sends over the delay you specify in the packet (which is what is done in this project also). I'll need to go back and log again to clarify this.

One fix is to just half the delay time (but it doesn't fix that -0.5ish dampener. I'd need to work out what exactly that dampener is).
