Add amiq_dsp_algorithms project. This example illustrate how to use
Octave built-in functions and how to connect Octave with System Verilog.

In this example 4 Digital Signal Processing functions (Fast Fourier
Transform - FFT, Discrete Cosine Transform - DCT, Finite Impulse
Response - FIR and Convolution) are implemented in System Verilog and
the results are compared with the ones computed by Octave.
