Should we add more audio formats?

[VitoVan]

The current allowed audio formats:

cl-sdl2-mixer/src/general.lisp

Lines 24 to 34 in fdcc7ee

	(autowrap:define-enum-from-constants (audio-format)
	sdl2-ffi:+audio-u8+
	sdl2-ffi:+audio-s8+
	sdl2-ffi:+audio-u16lsb+
	sdl2-ffi:+audio-s16lsb+
	sdl2-ffi:+audio-u16msb+
	sdl2-ffi:+audio-s16msb+
	sdl2-ffi:+audio-u16+
	sdl2-ffi:+audio-s16+
	sdl2-ffi:+audio-u16sys+
	sdl2-ffi:+audio-s16sys+)

:u8, :s8, :u16lsb, :s16lsb, :u16msb, :s16msb, :u16, :s16, :u16sys, :s16sys

But today SDL_AudioSpec has been updated:

https://wiki.libsdl.org/SDL2/SDL_AudioSpec

With more audio formats supported:
