feat(etls): add interreg 2014TC16RFCB014 - EUBFR-258

[kalinchernev]

PR description

Input file is in CSV format, however it's necessary to aggregate rows before they go to harmonized storage and value store (respectively), thus read and write are not streamed in this ETL.

QA Checklist

When you add a new ETL/producer, please check for the following:

• Ensure the ETL has been correctly setup following the guide in services/ingestion/etl/README.md
• There is at least 1 sample record.json and 1 unit test with a jest snapshot for the result of the transform function of the ETL.
• Ensure there is (flow/jsdocs) documentation in the transform function
• Generate the necessary documentation pages for the new ETL by yarn docs:md

Deployed and tested, all 97 projects have been imported ✅

Too bad we get a streamable file (CSV) but can't actually stream it (recordsAgg). I don't see any better solution for now.
