[Feature Request] Change Volume Mid-stream

[tionis]

As noted in #10 volume can currently not be changed mid stream without changing the code. It would be very handy for the encodingsession to expose a function that modifies a volume multiplier.

I just noticed that this functionality is already exposed in the encoding session options

Nevermind, I misunderstood the documentation, the original request remains, as it is not possible to edit the volume mid-stream
