Bump common-streams to 0.8.2-M1 and iglu-scala-client to 4.0.0

For this app, the most significant changes are:

- common-streams has a big change in how it preserves the order of
  struct fields: snowplow-incubator/common-streams#98. This should not
  impact how BigQuery loader works. But I highlight here because of the
  potential risk if we got something wrong.
- iglu-scala-client now treats both 403 and 404 as NotFound when listing
  a series of schemas from the Iglu repos:
  snowplow/iglu-scala-client#260
