Update to add OST event names for simonPhrase

[cwnaber]

This is required for simonPhrase to call audapter_viewer properly. I created #114 to address the fact that get_ostEventNamesNumbers should probably work out-of-the-box for simon experiments, but in fact requires updates to not error out.

[rpkarlin]

is the issue that the phrase experiments have multiple triggers?

@rpkarlin I'm going to move discussion about long term stuff to issue #114
