Implement initial design, and then some more
This is a very early version of the ACTS report tool. Given a pipeline number, it can extract test results from GitLab and render a standalone Excel document with the same information. The document has very basic style, but has all the relevant data. The first sheet contains the summary. Remaining sheets show data from a specific test suite.
