cli: Make example tests smarter

[matevz]

We have way too much .static examples meaning the output is not actually tested inside CI. I suggest we get rid of using .static for content that changes often and try to make a "smarter" diff.

For example, recent regression caused that ParaTime names got lost:

We should ignore the latest height, block hash and epoch in this case, but still test everything else.

Perhaps a kind of a regex "mask" per example that should define how the output should look like. So when you run "make examples" and the regex is matched, then don't generate the new .out files.
