feat(sltt-app): rollbar logging for compressor errors

[ericpyle]

with the old compressor window it was easy for users to copy and paste into an email the errors encountered.

We should report these errors to rollbar in sltt-app.

We may also want to install a rolling logging library to keep track of all the console log history. Then we could attach those files (or at least the latest one) to rollbar reports

Current Workaround:
There is a way to launch sltt-app from the command line which should show console.logs related to the compressor, but that would only be helpful if users are stuck by the compressor error. It wouldn't help for errors that are not as reproduceable
