Implement file compression

[bennavapbc]

🎫 Ticket

https://jira.cms.gov/browse/AB2D-6462

🛠 Changes

• Add utilities for compressing job output files to gzip format
• Allow bulk download API to return compressed or uncompressed files (per request header)

ℹ️ Context

• Compress job output files to reduce file size by ~90% and (slightly) improve transfer times for clients requesting compressed files

SonarQube

🧪 Validation

• Added unit tests and integration tests in TestRunner
• Verified that output files generated and stored in uncompressed ndjson formats are still able to be downloaded
• Deployed to IMPL and tested (a) status and (b) file download APIs work as expected for both /v1 and /v2

Verified file length and checksum match download files after decompressing

Verified a curl request with Accept-Encoding: gzip returns compressed data along with content-encoding: gzip response header

curl -v -w "@curl-format.txt" -X 'GET' \
  'https://impl.ab2d.cms.gov/api/v1/fhir/Job/f1354d5c-1111-bbbb-cccc-dddddddddddd/file/Z0000_0001.ndjson' \
  -H 'Accept-Encoding: gzip' \
  -H 'accept: application/fhir+ndjson' \
  -H "Authorization: Bearer $JWT" -o Z0000_0001-speed-test.ndjson.gz
Note: Unnecessary use of -X or --request, GET is already inferred.
