Add SRC component

This change provides a sample rate converter (SRC). The SRC is polyphase FIR type. All the conversions coefficients tables are automatically generated by a separate Octave scripts set in the rimage tools set. The supported in/out rates and the performance can be customized for a different quality/resources trade-off.
