Isn't there some redundancy here now? endianness/width/depth are
expressed by the format already.

If only the GstAudioFormat stays it will be impossible to have, e.g. 16
bit samples in 4 bytes, which is something that some codecs would
require and we would need to do conversions inside the element then.

Also, can we get support for non-interleaved channels now that
everything is changed anyway? Just add it as an additional flag to
GstAudioFlags :)
