Re: [encrypted-media-tests] [eme] Updates to multi-session sequential tests (#3629)

#3447 It had two copies of each pssh box.

It was previously organized around whether there were multiple keys (as well as whether there were multiple session). In fact we do not need to distinguish the single-key single-session case from the multi-key single-session case: the same test script can be used for both with different parameters.

The multi-session script can also be used both for the case of separate keys in audio / video and of multiple keys used in every fragment.

We'll need a new script to re-instate the originally intended case where one key is used for a few seconds followed by another key. This may actually be two cases: one to check we get waitingforkey and can continue playback and another to check that playback can happen seamlessly if both keys are there at the start.
