v8.0.1 - Fix HLR Lookup Type Mismatch

🐛 Bug Fix

Fixed HLR Lookup Type Error

Problem:

• HLR lookup was failing with TypeError: Cannot assign int to property LookupHlr::$gsmCode of type ?string
• This occurred after the seven.io API was updated to consistently return gsm_code as integer instead of string
• Affected users on PHP 8.2+ with strict type checking

Solution:

• Changed LookupHlr::$gsmCode property type from ?string to ?int
• Updated getGsmCode() return type accordingly
• Updated tests to expect integer values
• Fixed README HLR example with correct method names

Impact:

• ✅ HLR lookups now work correctly with the updated API
• ✅ Type-safe handling of GSM error codes (0 = no error, 1-255 = error codes)
• ✅ No breaking changes for existing code

Files Changed:

• src/Resource/Lookup/LookupHlr.php
• tests/LookupTest.php
• README.md
