This commit fixes the audio_rtttl example (which was undocumented and previously used kernel-level functions) such that now it uses the RTTTL parsing library. Contributors can implement 'players' for different types of audio sinks. Currently, PWM is supported. BREAKING: The previous version of this example only supported a single board (Spresense) and uses public interfaces from the kernel code. Now it only uses user-space interfaces and supports any board implementing those interfaces. Users who relied on the old behaviour should submit a patch to add a new player to this application which uses the desired audio sink for the Spresense through user-space interfaces.
