Tweaked WAVE audio file reader method arguments.
Tweaked WAVE audio file reader method arguments.

It didn't make much sense that one could override a value of the
`mono_1d` argument to the `WaveAudioFileReader` initializer with a
different value of the argument of the same name of the `read` method,
so I eliminated the `read` method argument.
