Allow setSoundPosition to be used with file streams

[StrixG]

The setSoundPosition function can now be used with file streams and returns false if the position can't be set (e.g. the sound is a live stream or the buffer has not yet reached it).

I tested this and was unable to get it to work using an mp3 file please show test code that shows this PR working.

Test resource: sounds.zip

Video of the test: https://www.youtube.com/watch?v=uup8snl5UQk
Enter splayurl https://yamamichi.me/1.mp3, wait until the sound is downloaded and use spos 100.
Or just use this code:

local s = playSound("https://yamamichi.me/1.mp3")
print(setSoundPosition(s, 100)) -- false

setTimer(function ()
    print(setSoundPosition(s, 3)) -- true or false (depends on your internet connection)
end, 3000, 1)

addEventHandler("onClientSoundFinishedDownload", root, function (length)
    print(setSoundPosition(s, 120)) -- true
end)

Thanks for this @StrixG - your test resource works perfectly. @ArranTuna - if you can sign-off that this works for you now, we can go ahead and merge this.
