add method to get audio position about corona

[super-toki]

This is an unofficial API, but you can use it.

local handle = audio.loadSound(filename)
local ch, src = audio.play( handle, { channel=1, loops=0 } )
local function onFrame(event)
        local position = al.GetSource(src, al.SEC_OFFSET)
        print(position)
end
Runtime:addEventListener( "enterFrame", onFrame )
