This version also includes changes to the AMBE codec interface code, back-ported from the latest STM32 version. This version now uses -Os code optimisation on all source code files, whereas pervious many files were accidentally being compiled with no optimisation -O0 Thanks to SASANO Takayoshi (JG1UAA) for his help with these changes
