Add support for Android OS

[yayameen]

Is Android currently targeted for support? I am interested in the capability to read and write different audio formats. Android an iOS are currently absent from the list on the main page. Thank you for all the great work, BTW.

Most extensions are dependent on / include native libraries which are OS and architecture-specific, so those will have to be precompiled and included. I'm currently working through some ARM compatibility stuff for MacOS 11+. The other potential issue is that I haven't tested on mono (shouldn't be much of an issue now, as .NET 6.0 is supposed to work on Android / iOS). Then there is packaging - dynamic updating of extensions might not make the most sense on a mobile device. Anyway, its certainly possible but not something i've looked at just yet.
