fkYAML v0.4.4

A C++ header-only YAML library

Release notes

# What's Changed
## :sparkles: New Features
- Add fuzz test for parsing YAML inputs #537 (@fktn-k)
    - Currently, it can only built with a Clang compiler. With GCC or MSVC compilers, the build fails.
    - You can run the fuzz test with sanitizers enabled by running the following commands.  
      ```bash
      $ cd /path/to/fkYAML
      $ cmake -B build -S . -DFK_YAML_BUILD_TYPE=Debug -DFK_YAML_BUILD_FUZZ_TEST=ON
      $ cmake --build build --target run_fuzz_test
        # The results will be output to the `build/tests/fuzz_tests/corpus` directory.
      ```
- Add get\_resolved\_tag\_name API to basic\_node #559 (@fktn-k)
    - This method returns a resolved tag name by replacing a tag shorthand (`!!` or `!e!`) with the prefix defined in the %TAG directive.
    - This would be useful if you would like to perform some special operation based on tag properties associated to the target node, given that the pre-existing `get_tag_name` returns an unresolved tag name.
    - See [the API reference page](https://fktn-k.github.io/fkYAML/api/basic_node/get_resolved_tag_name) for more details.
