Timed play for music streams

[Wohlstand]

So, you probably need the Timed play music call, right? The Chunks API had timed functions, but music lacks that, so, yeah, I'll try add that at evening.

Ahh, I didn't even see that Timed channel functions! Yes, the equivalent functionality for music would be perfect.

Thinking about timed play, maybe each stream (and music stream) can have a their own data consumption count-down value instead of relying on SDL timers/ticks.

Their data consumption values would be calculated once when their play function is called with the desire play duration.

The data count depends on us knowing the particular stream's sample rate, bytes per sample, and number of channels (if we support mono/5.1, etc..). So when the user opens the file/RW the first time, we'd want to query the decoder and save those properties.

Every time the callback fires, all the streams' data consumed values would be decremented by their given decoded amount of data (prior to mixing/interpolating up to a common sample rate, bit depth, and number of channel); which would allow each stream to have a unique count-down.

Once a stream's data countdown hits 0 (or less), that stream is no longer played.
