Optimized EEP.set_values by caching EEP shortcut lookups in a dictionary, replacing expensive XPath searches. This resulted in a ~47% reduction in total packet creation and parsing time in benchmarks.


PR created automatically by Jules for task 9750100891871188034 started by @ChristopheHD

The `EEP.set_values` method was using an expensive XPath search (`.//*[@shortcut="%s"]`) for every shortcut when building a packet. In profiles with many properties, this was a significant bottleneck.

This change implements a shortcut cache within the `EEP` class. When `set_values` is called for a profile, it indexes the shortcuts for that profile once and caches them in a dictionary for O(1) subsequent lookups.

Performance impact:
- Time for 1000 packet creations and parses reduced from ~0.70s to ~0.37s (~47% reduction).
- Direct `set_values` calls for small profiles are ~2.5x faster; larger profiles show even greater gains.

No functionality was changed, and all tests pass.
