chore: #710 make analysis settings private

[ArdtK]

Issue addressed

Solves #710

Code of conduct

• I HAVE NOT added sensitive or compromised (test) data to the repository.
• I HAVE NOT added vulnerabilities to the repository.
• I HAVE discussed my solution with (other) members of the RA2CE team.

What has been done?

Instead of removing AnalysisConfigData.static_path (is required to get origin-destination info), it is made private, along with other properties that should come fromt the NetworkConfigData:

• root_path
• network
• origin_destinations
• aggregate_wl
  Remove private properties from initialization of AnalysisConfigData in notebooks.

Checklist

• Code is formatted using our custom black and isort definitions.
• Tests are either added or updated.
• Branch is up to date with master.
• Updated documentation if needed.
