missing kiss_fftnd from libkissfft.so

[utkarshayachit]

The primary library libkissfft.so doesn not include .*_fftnd APIs. Why is that? Are they not part of the public API? Is they are, would it make sense to built it in the toplevel Makefile itself?

kiss_fftnd.c isn't compiled into the .so by the main level Makefile, and the makefile in tools just builds the fft_float executable, which doesn't expose a low-level API offering fftnd - it likely wouldn't be hard to fix this, but I don't have the bandwidth right now.

to directly answer your question - there's no reason I have not to expose _fftnd as a first-class API - the original author didn't, but it seems like a useful abstraction to include in the scope of the top level API.

thanks! I'll have a pull request when I get around to it.
