This adds a very basic way to perform expected comparisons (without an update script).
We test that the Test entrypoint returns the same stdout/stderr.
I do some chores in the same PR.
Contributes in a very rudimentary way towards #9, from what I see, mathlib4 does not have an expected output verification but does have a silent verification mechanism for many tests/ elements, I don't know if we want to repeat this or fan out to many tests and verify their output all the time à la Lean 4.
