add status flag

[rsese]

closes #12

Adds a -s / --status flag so you can filter by workflow run status (https://docs.github.com/en/rest/actions/workflow-runs?apiVersion=2022-11-28#list-workflow-runs-for-a-workflow)

ran it locally -- first with everything:

❯ go run main.go  cli  -r"cli" -l 4h            
                                                                      GitHub Actions dashboard for cli for the past 4 hours                                                                      
                                                                                    Total billable time: 0ms

then with just failures:

(a flag to hide the No runs would probably be good too 🤔 )
