Add a setTimeouts(timeoutMs: number) method to configure manually the timeout of every request

[TMSCH]

The signature of the method should be:

OpenYoloApi.prototype.setTimeouts(timeoutMs: number): void;

We can remove the setTimeoutsEnabled() in favor of the new method, by considering a 0 as timeouts disabled.
