[encrypted-media] Define key ID sort order

ddorwin has just created a new issue for 
https://github.com/w3c/encrypted-media:

== Define key ID sort order ==
The fix for #39 added the text "sorted by key ID."

Since a key ID is just an array of bytes, we should clarify what it 
means to be sorted by key ID. Are bytes compared from byte 0 to N or N
 to 0? What if the key IDs have different lengths?

This also depends on defining the representation (#68).
