2.0.0 New interface, value objects, exceptions & more

Refactor BCP47Tag library to give better results, understandable interface, exception and performace

• Refactored BCP47Tag class, changed class construction signature.
• Replaced $knownTags and $requireCanonical arguments with $useCanonicalMatchTags array
• Refactored the internals during construction of the object to better handle fallback, normalization and validation (including fallback and useCanonicalMatchTags array)
• added public interface getLanguageTag(): LanguageTag method so you can work with even easier value object in your code base,
  useCanonicalMatchTags is now using scoring system to match the resolved language tag to provided list
• ParsedTag value object is now Stringable and JsonSerializable
• Introducing LanguageTag— an immutable value object that can be created only via it's own factory method and extending ParsedTag so it's also stringable and json serializable
• BCP47Normalizer now uses auto-generated GrandfatheredTag enum to detect grandfathered tags
• Few modifications to BCP47Parser to more readable, throw exceptions, and handle grandfathered tags correctly
• Few modifications to IanaSubtagRegistry to throw exceptions, added TODO list what is missing and made code more readable
• Resource file is now static php array instead of json file
• Resource file compilation how expands range tags into individual tags/subtags, uses utility function expandAlphaRangeFunction()
• Made Exception classes with a logical flow in case something goes wrong
• Added phpstan/phpstan-strict-rules into composer
• Added composer iana:refresh to fetch and compile fresh source of data
• Some more...

This version if far more ready to work great on production environments for 99.8% of the cases that might be needed :) While I still see the joy to work towards the goal to make the 0.2% happy as well (flex)

1.0.1 Switch to static PHP IANA registry, remove symfony/intl, optimize lazy loading and add git workflow with QA tools run

• Replaced JSON IANA registry with static PHP snapshot for zero parsing overhead
  -Removed symfony/intl and validator dependency (not needed after refactor). Remnant of the original thoughts.
• I mplemented singleton lazy loader for registry (friend of OPcache)
• Updated composer with iana:refresh script for manual IANA updates
• Cleaned up normalizer logic (pure ABNF-based, no external fallback)
• Updated README to reflect new structure and performance design
• All tests green, code lighter, faster, and fully self-contained. Ready to handle more serious loads.
• Create git workflow with php.yml
• Added getICULocale() instead of getUnderscored()
• Marked methods getLC(), getUC() , getLCU() and getUCU() as internal (however, you can still use them if you're in lazy mode)
• Added git workflows to run the build and QA tests
• Updated tests
