Added sos2tf() function to convert SOS to Transfer Function coefficients like matlab's SOS2TF #10

Hello, I have added some features in my fork of this project.

They are:

Added sos2tf() function to convert SOS to Transfer Function coefficients like matlab's SOS2TF.
Added conv() function to do convolution.
Added CMake as building system, and move tests to 'tests/' subdirectory. Because I do not use SConstruct so I didn't change it, but changed the doc to cmake.
Added some cross-compile support for arm64 target, but they are specific to my development environment.

If there are something wrong, please tell me. : )

Add bandpass test. Found a1,a2 are negative compare to the matlab results.

The reason is wrong to use #undefin instead of #define

With a1,a2 * -1.
