change blast_stats.json schema to add new fields

Change the blast_stats.json schema to add new fields from the documentation here

Ran a test meltano elt into nymag-analytics-157315.dev_meltano.dev_blast_stats with the new schema

Would we want to manually update the DDL for the target table? Also any changes needed downstream, like the dbt models?

As discussed, rather than changing the DDL, feels easier to just delete the current prod tables and full refresh them.
As for dbt changes, yeah we'll need to make some to incorporate the new fields/schema, but ran a test on the stg model against my dev table and it ran successfully -

With the last commit, we're going to try ignore_parent_replication_key = True since the replication key for BlastStream is start_time and we don't expect that to really change per record. Adding this config will pull the latest blast_stats for each blast, so the ingestion will take longer but we will have the freshest data. Docs here

Also added a few more fields to the blast_stats.json schema.
