ULC/CCC/BC pipeline - update to support alteration filings

This ticket is to update the pipeline to support alteration.

This will include:
* Updating raw sql queries to pull in required data from COLIN db extract
* Updating code to generating filing json for given filing
* Update custom filer code to process generated filing json
* Testing pipeline against a decent sample size to see what errors come up

When updating the pipeline to support a given filing, the initial testing will be done locally against a COLIN db extract. We can test with a smaller but significant sample size of fillings to have a certain level of confidence that the pipeline is working in general for a given filing.

In our overall migration testing, all migration of prod COLIN corp data will be tested. Under this comprehensive testing, various data issues and edge cases will be discovered for various filings. We will cut tickets at this time to address the issues that come up.

Start by locating the raw SQL queries, filing JSON generation code, and custom filer code described in the issue, then review how the pipeline handles existing filing types. Run the pipeline locally against a COLIN database extract with a smaller significant sample. Done means alteration filings are processed end to end and sample testing identifies no general pipeline errors.
