AI Packages - the following fields can appear in any order, one per AI package, with the order defining the package priority.

Note: duration parameters in all packages are in hours. Any value greater than 24 should be divided by 100, and set to 24 if still greater than 24. The unknown value for each package seems to be an end-of-data marker; it is always a byte value set to 1 with any remaining data in the structure undefined and ignored.
