Create a WebASM tool to allow us to properly estimate the byte size of a song.

Would be awesome to have a WebASM version of ATMLib that would ideally do a proper sizing of the data via the macros, etc..

@jaygarcia could you please add more details on this one, trying to understand what has to be done here, and don't think you want the ATMLib to be ported in WebASM. Which macros ? an example how the sizing is done would be helpful to see
