[PD] better tabread4~

i'm still trying to understand why pd sound quality is not very good.

i realized that the 4 points interpolation in tabread4~ (and tabosc4~) are not optimal. 
so, i just made few objects to replaced them (most of the code are copy from pd sources), but using a true 4 points cubic interpolation.
i personally consider this to sound better than the pd version (specially with small tables), and they did not use more cpu.

this objects (located in svn/externals/nusmuk/tab/) are just for test, but they can fully replace the standard tabosc4~ and tabread4~.

i think higher order interpolation can be useful for even better audio quality, but i'm wondering if someone already worked on this.
if not, i'll like to make a few tabread equivalent with diferents interpolation schematics (when i'll have more time...).
