Add continuous integration support and fix the pipeline

There are several things keeping Nofib CI from happening right now:

• No .gitlab-ci.yml script. Fixed by adding a script.
• Booting compress2 was broken. Fixed by comparing hashes as in !2 (merged).
• Test output mismatch in fasta. Just forgot to pass mode=fast to make boot.
