[iOS Support Incoming] - AVAudioEngine bindings

[Hipreme]

Today, I've come to announce that bindings that works for both 
macOS and iOS have been done, which is soon to be integrated with 
[Hipreme Engine](http://github.com/MrcSnm/HipremeEngine)


Those bindings are on [AVAudioEngine Bindings 
Dub](https://code.dlang.org/packages/avaudioengine).

They depend on a new dependency I've also put on dub, which is a 
base for [Creating Objective-C 
Bindings](https://code.dlang.org/packages/objc_meta)

On the AVAudioEngine repository, there is a simple script I made 
with Javascript for converting partially an Objective-C file to 
D, which helped me assembling those bindings.
