feat: add report generation as cli

The previous way to get reports required users to upload their data to ObservableHQ. Based on our experience, we expect customers to be wary of sharing anything about their code with third parties. This change allows users to create reports locally without their data going to any third party.

The change was kept to a minimum on purpose. There is no archiving or serving of files from within the tool as better tools exist for that purpose, and users can use their preferences to achieve this.

Things left:

[x] Add copyArtifacts function to copy the output of the report to a findable directory
[ ] Integrate download_report_files.sh into one of the pipelines
