jetRatio

Hi there,
am I wrong or the current use of `jetRatio` is wrong?

This line https://github.com/timowest/flute-lv2/blob/master/faust/flutelib.dsp#L59
is 
```
jetDelay = fdelay(4096, SR / freq * jetRatio);
```
should it not be 
```
jetDelay = fdelay(4096, SR / freq / jetRatio);
```
instead?
