Missing prefix ma. in PI and SR in notchw

[Juan Sierra]

Hey I hope Im not bothering too much lately, but it seems like the symbols for PI and SR are missing the ma. prefix in the filters.lib library in the notchw filter.

faustlibraries/filters.lib

Lines 496 to 500 in 9c5c152

 wn = PI*fb/SR; 
 b0db = 1.0 / (1 + wn); 
 p = (1 - wn) * b0db; // This is our pole radius. 
 // Now place unit-circle zeros at desired angles: 
 tn = 2*PI*freq/SR; 

I hope this helps
