feat: add exclude_penalty_shootouts parameter for event data loading

[DriesDeprest]

Context
Sometimes, when analyzing event data, we want to exclude actions that occurred during the penalty shootout, as including them can distort player statistics such as shots and goals.

Functionality
Add support for excluding penalty shootout events (period 5) when loading event data across all providers. This feature provides complete cleanup of penalty shootout data from the dataset.

Changes

• Add exclude_penalty_shootouts parameter to EventDataDeserializer
• Implement should_include_event() filtering for period 5 events
• Add remove_penalty_shootout_data() method to clean up metadata:
  • Removes period 5 from metadata.periods
  • Updates period references (prev/next)
  • Removes player positions for period 5
  • Removes team formations for period 5
• Update all provider load functions to support the parameter:
  • StatsBomb, Opta, Wyscout, DataFactory, Impect
  • StatsPerform, Sportec, Metrica
• Add comprehensive tests in test_event.py

The parameter defaults to False for backward compatibility.

Let's rewrite it as a method on the (Event)Dataset instead of an argument in the deserializer.
