Add rtpL24depay / rtpL24pay elements

This is part of RFC 3190, which also lists DAT12 and L20 as extensions. I'm just considering if we need an ARAW de/payloader that handles all these raw formats or keep on duplicating the audio de/payloaders. It would make for less code but then there would not be a direct mapping between the encoding-name and the payloader anymore.

For now, let's just duplicate it to keep things consistent.

Would,
 - renaming these elements to something more generic (rtparawpay / rtparawdepay?)
 - requiring that a 'sample format' be specified (but initially only allow the value S24BE)
 - otherwise keeping the code the same

make for an easier transition to one-element-for-all-formats, or just be too confusing?

I don't mind doing some basic rearrangement if it makes the code more useful -- bearing in mind that I am new to gstreamer and glib APIs!

I think it's a bit confusing for now.
