Include iOS in AudioFormatManager::registerBasicFormats

Hi there, just a small request for AudioFormatManager::registerBasicFormats, would it be possible to change line 64 to #if JUCE_MAC || JUCE_IOS so that the CoreAudioFormat gets registered by default on iOS. This just stops me having to add it myself and ifdef the register so it doesn’t get added twice on a Mac build.

Yes, of course! Sorry, I didn’t realise I had missed that out! Thanks!
