This PR updates the IP data structure to match the latest API response format and modernizes the project's dependency management.
Summary
Updated the
IPstruct to include new fields (RegionCode,EmojiFlag) and corrected existing field mappings. Additionally, migrated fromdepto Go modules for dependency management and removed vendor directory in favor of module-based dependencies.Key Changes
IP struct updates (
types.go):RegionCodefield to capture region/state codesEmojiFlagfield for emoji flag representationEmojiUnicodefield to store the correct format (removed quotes from JSON tag)LanguagesJSON tag fromlanguagetolanguagesDependency management:

The struct field changes ensure proper deserialization of the IP geolocation API responses, particularly for region codes and emoji flag representations. The migration to Go modules simplifies dependency management and aligns with modern Go best practices.
