Polyphonic Sampler Devlog 3

I was adding a bunch of audio related stuff and code to start adding polyphony!!

• There is 8 audio stream players, one for each voice.
• There is a new ‘audio’ code. Instead of the audio being activated in the scene node, it will be activated by audio players themselves. This new script will be attached to each audio player and will take advantage of arrays
• Made a release helper variable an array for each voice. The same will happen to other ASDR soon but first I need to make sure that the 8 voices work with varying release functions.
