DMtimer seems to block after some time - Long overflow ?

[Koraze]

Hi, sorry for my bad english.

I build an ESP8266 (NodeMCU) robot and it seems your lib blocks the robot after some hours. I think it is because of long overflow inside your code. After some time the "currentTimer" turns back to 0 making this condition "if(currentTime > _lastTime + interval)" not working anymore. So I suggest you to make this small fix :

Remplace if(currentTime > _lastTime + interval)
by if(currentTime - _lastTime > interval)

Because it's my first time on github. I don't really know how to propose this fix in another way.
I'm testing this new fix right now. If I don't go back, it's because it seems to work ;)

Thanks for your lib

Hi @Koraze,
First : SORRY for the delay.
You are right, I just corrected the test according to your hint to ensure it works even after overflow :)

Cheers
