fix macOS build (following Projucer changes made in Windows, which removed /Applications/JUCE/modules from its headers). move JUCE headers under source control, so that Windows and macOS can both build against same version of JUCE. remove AUv3 target (I think it's an iOS thing, so it will never work with this macOS fluidsynth dylib).

Represents a set of audio channel types.
For example, you might have a set of left + right channels, which is a stereo
channel set. It is a collection of values from the AudioChannelSet::ChannelType
enum, where each type may only occur once within the set.
The documentation below lists which AudioChannelSet corresponds to which native
layouts used by AAX, VST2/VST3 and CoreAudio/AU. The layout tags in CoreAudio
are particularly confusing. For example, the layout which is labeled as "7.1 SDDS"
in Logic Pro, corresponds to CoreAudio/AU's kAudioChannelLayoutTag_DTS_7_0 tag, whereas
AAX's DTS 7.1 Layout corresponds to CoreAudio/AU's
kAudioChannelLayoutTag_MPEG_7_1_A format, etc. Please do not use the CoreAudio tag
as an indication to the actual layout of the speakers.
