Adds back the removed portable installation method, but in a different way that shouldn't be possible to mess up. The original method had to be removed due to an excessive amount of poor video guides on how to install StreamFX, many of which went out of their way to ignore the Installation Guide.
Fixes#542
Enables users of the Mac Operating System to use an automated installer instead of the manual installation method which is prone to user errors. This is done via the use of "Packages", which generates a .pkg file according to the requirements we present it.
A complete redesign of the component and dependency system is necessary in order to support additional platforms, such as MacOS and other Linux platforms. Additionally it results in a much cleaner code base, which is less confusing overall.
Eventually it might be necessary to push components of StreamFX into their own CMake projects, as it is getting kind of complex now. Especially with the push for a proper plugin manager, things get dicey for big plugins like StreamFX.
