Human summary printer: run detectors only once

[montyly]

Currently the human summary printer will run the detectors for each contract, instead of running them once.

As the result, the human summary printer can take a significant amount of time for large codebase

[montyly]

In addition the human summary printer has in its json output the detectors results.

The results are in the ["additional_fields"]["detectors"'] field of the printer
