Additional library needed for soxr.h

Hi, I just tried to compile this on a fresh Raspberry Pi OS (2022-01-28) and got this message while compiling:

I then installed the libsoxr-dev package with sudo apt install libsoxr-dev and it compiled successfully afterwards. Could you update the install instructions in the README?

Thank you so much! That worked!
