fix: character death entry with lowercased of-creature

[tobiasehlert]

This pull request improves the handling of creature names in the killer parsing logic and adds a new comprehensive test case to verify death data parsing for a specific character. The main changes focus on increasing the robustness of string matching for special creatures and expanding test coverage for death parsing scenarios.

Parsing improvements:

• The containsCreaturesWithOf function now converts input strings to lowercase before matching, making creature name detection case-insensitive and more reliable.

Test coverage enhancements:

• Added a new test TestNumber18 in src/TibiaCharactersCharacter_test.go that verifies the parsing of death data for the character "Tirador Azteca," including detailed checks for killer names, death reasons, levels, and timestamps.

fix #504
