CLI to re-encrypt data in tfa_user_config table, closes #8

[cjnewbs]

Fixes #8

Summary

• CLI command to re-encrypt values in the tfa_user_config table based on https://github.com/genecommerce/module-encryption-key-manager/blob/master/Console/ReencryptColumn.php,
• I have commented Model/RecursiveDataProcessor.php more than normal purely due to the fact it's recursive so wanted to add more verbose overview of whats happening.
• Opened as draft for reviews/feedback whilst I continue testing/validating my changes

Example output

The 2FA details can contain encrypted data within a json payload, which is also encrypted. So we navigate down and decrypt those values.
