Quality of life verifier cli options

[jonathan-boudreau-work]

There are several options that I often use when I'm developing tests (e.g., pytest, jest, etc) which would be great to also have in the verifier IMO:

• --exit-first: Stops the verifier at the first failure. This would be useful if you want to stop at the first failure so you can check the state of the provider to make sure things are set up correctly.
• --last-failed: Only re-runs the interactions that failed on the previous verifier run. Lets say I fix an issue with the state setup, or the contract itself, I don't want to re-run the whole suite to just check if my fixes are resolved.

I've released 1.2.0 with these options:

• --exit-on-first-error (I renamed it to make it more explicit)
• --last-failed which requires the --json output option
