Description

Since we move a lot of parameters to substruct of the x struct, I thought it would make sense to initialize them correctly. This way we don't have to check their existence every time.

Requirements

Implement a function called ExploreASL_Initialize_SubStructs.

How to test

I don't think this can break anything. The only possibility would be if we only create some fields if they don't exist already.

Release notes

Minor initialization improvements related to revamp of #480.
