Handle analysis of demos

[megascatterbomb]

Adds endpoints and functionality for analysis client and record-keeping. This PR has been tested in production for the past few months.

Workflow is as follows:

• Analysis client is set up separately with an analysis API key.
• Analysis client uses /jobs endpoint to pull session ids in need of analysis.
• Analysis client uses existing /demodata endpoint to pull demo file.
• Analysis client uploads results via MinIO and notifies masterbase via /ingest endpoint
• Masterbase ingests the data by ingesting analysis json from MinIO and copying detection counts into analysis table.
