cli to automate some manual gst1 update work; do gst update

[kdutia]

two CLIs to automate the work of updating gst1.

1. 1_get_new_parser_outputs.py: compares a new UNFCCC to an old one, goes and grabs the ParserOutput docs from S3 to process
2. 2_run_concept_extraction.py: imports explorer and runs concepts. parametrised only by the folder name (i.e. the download folder from the first step

step 3 is then to run the indexer, and 🎉

the missing part at the moment is having all the documents in one place: they're in a local directory for me. I can drop them into an s3 bucket if someone else ever needs to run this, but am cautious to create yet another folder on s3 until we've done our data consolidation work with deng

note CI is failing because we now install explorer as a dependency and GH actions doesn't like installing from git apparently - but everything else is ready to review
