audiosample: convert to use a protocol
...
This eases addition of new sample sources, since the manual virtual
function dispatch functions are just calls via a protocol

Allow to specify pre-allocated buffer in audicore.WaveFile
...
It lets us re-use the same buffer for playing multiple files.
This also allows us to control the size of the buffer. Half of the
buffer will be used for the fist, and half for the second internal
buffer.

audiocore: Factor from audioio
...
When nrf pwm audio is introduced, it will be called `audiopwmio`. To
enable code sharing with the existing (dac-based) `audioio`, factor
the sample and mixer types to `audiocore`.
INCOMPATIBLE CHANGE: Now, `Mixer`, `RawSample` and `WaveFile` must
be imported from `audiocore`, not `audioio`.
