[PD] a slightly nicer saturator than tanh~

[Miller Puckette]

Also try arctangent in place of tanh.  Its asymptotic behavior is
1/x instead of e^(-x) which makes for softer clipping.

I often make a big table to speed up the atan lookup using tabread4~ although
you have to be careful at the table limits.
