* Separated tests in multiple files.
* Added pydantic validation for configuration.
* Improved backup/restore on visit of nodes.
* Echoing of variables with default no longer visits the default when not used (and no longer creates variables that were not actually used).
* Mapping of extranetworks through the new command. This allows you to use a "virtual" extranetwork that is converted to a real one depending on conditions, like the model kind/variant.
* Fixed a parsing bug with the if command.
* Some refactoring and additional checks.
