ReaScript FR: LU and LUFS function

[X-Raym]

Thanks to @nofishonfriday, we now have max peaks and RMS function for ReaScript. Good !
#781
But I think it could be very intersestig to also have LU and LUFS used in SWS Loundess Analyser like

lufs = GetMediaItemLUFS( item )
lu = GetMediaItemLU( item )

We can also imagine this being used on Take instead like

lufs = GetMediaItemTakeLUFS( take)
lu = GetMediaItemTakeLU( take )

This kind of calculus is hard to make from scratch with Lua and regular audioprocessor tools so having this in ReaScript could be very interesting :P

Thanks for listening !
