Timer.start() initial time

[LekloOno]

Very simple, I would like to be able to set the initial time on a Timer, when calling start().

My use case :
I use a timer to loop a sound play, I try to avoid using _process/_physics_process constant checks, and to rely as much as possible on event based principles. I just discovered Timer, and it's nice for this use case ! But I can't set an initial time, time_left is read only.

Just setting the wait_time differently would work, but it would mean I'll have to do some additionnal checks -

1. Start the timer with the initial wait time
2. In response to the first timeout, "do things" AND set the timer wait time to the real loop length AND set the new listener of timeout to just "do things".
3. In response to the other timeouts, "do things".

I could also set the timer to one shot, and call it recursively, but it kind of defeat its purpose.

I think it would be usefull to add an optionnal parameter to start() for the initial time_left.
