Calling api.SetDelay() as mentioned in readme panics

[ahmetb]

If you do this:

You get the panic:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x11cd32]

goroutine 1 [running]:

because api.bucket field is nil.

I had a similar issue, but I found a fix

It looks like you have to call api.EnableThrottling() first, then you're able to call api.SetDelay().

The README section on throttling notes that throttling is off by default, but it would be nice to have a nice one-liner that tells the user how to enable Throttling (and explain a little more about the bufferSize argument in the EnableThrottling() function call)

+1, four years later I'm getting the same issue.
