Sawtooth via 4th order differerentiated polynomial waveform

Description

Differentiated polynomial waveforms described in their technicalities here: Vesa Valimaki, Juhan Nam, Julius O. Smith and Jonathan S. Abel Alias-Suppressed Oscillators Based on Differentiated Polynomial Waveforms IEEE Transactions on Audio, Speech, and Language Processing 18(4) May 2010, pp 786--798

Internally, uses DPW2 (quadratic polynomial) for frequencies below 400Hz, with a crossfade in the 400-600Hz region to DPW4. DPW4 behaves well then for higher frequencies.

Slightly less efficient than Saw when lots of UGens running, very slightly duller sound.
