Add input capture for allure reporting

[PatStLouis]

This will capture requests and response sent to the issuer/verifier for every call made, useful for debugging.

To avoid this creating unnecessary noise when running with the db reporter, the console logging is disabled when calling the attachment function.

I like it. Can you add info to readme on how to use it?

As long as #134 goes in first. 😁

@PatStLouis is Allure already configured for the weekly report runs? What happens if Allure is turned off or not configured (or goes missing / is down)?

@tminard there is a section about running allure, you just need to initialize the tests with npx mocha tests/ then build the report with npx allure serve

The rest is automagical, just need to browse the report and the payload will be attached to their associated tests.

@BigBlueHat currently this is all configured to be run locally, no standing allure server is setup. I can set one up if we want to explore this further.

The way its currently implemented, a user runs the test locally and runs the allure server from the command line The report will be available from the local host.
