Fuzzing support cont.

[szszszsz]

This PR handles the latest protocol change for the oath-authenticator app, and its fuzzing support update.

Changes

• Handle the protocol change for the oath-auth, where the response got prefixed with the precise error code.
• Write down all commands sent per given test case (for multi-command fuzzing)
• Update test cases with the new error names
• Translate error codes to HR readable format, when showing to user
• Reuse NK3 connection during the tests execution
• Add passphrase clearing test
• No UI changes
• Add Earthly based setup for setting up development environment (required since nitropy does not work under Python 3.11)

Checklist

• tested with Python3.10
• run make check or make fix for the formatting check
• signed commits
• updated documentation (e.g. parameter description, inline doc, docs.nitrokey)
• added labels

Test Environment and Execution

• OS: Linux Fedora 35
• device's model: USB/IP simulation, Nitrokey 3 CN
• device's firmware version: 1.2.2 alpha

Connected: Nitrokey/trussed-secrets-app#15

Future work / to discuss:

• remove return type from verify_code
• code style: use enum instead of strings for error names in OTPAppException? (and compare later by enum value) - TBD Refactor ISO7816 status codes #297
• describe taking samples for fuzzing (see https://github.com/Nitrokey/oath-authenticator/tree/main/fuzz#generation)
• better pytest Exception matching?
