#204 introduced an error in https://github.com/pschatzmann/arduino-audio-tools/blob/c88d3b9f132555ab7cd932a53744fa6c42aa8e0f/src/AudioPWM/PWMAudioRenesas.h#L90 (due to type confusion between int and float).

Proposed fix: change the signature of begin(uint32_t, uint32_t, ...) to begin(int, int, ...)
