This pull request enhances the BinarySerializers class by adding comprehensive Javadoc comments.
The added documentation provides detailed explanations for each serializer and factory method, improving code readability and usability.

Key updates:

• Class-level Javadoc: Introduced a summary of the BinarySerializers utility class, describing its purpose and usage.
• Serializer Documentation: Added Javadoc comments to all public static serializer instances (e.g., BYTE_SERIALIZER, INT_SERIALIZER), explaining what types they handle and how they function.
• Factory Methods: Provided detailed descriptions for factory methods like ofOptional, ofNullable, ofList, ofSet, ofMap, and ofEnum, including explanations of parameters and return values.
• Parameter and Return Details: Ensured all methods have clear documentation on their parameters, expected inputs, and outputs.

Benefits:

• Improved Developer Experience: Makes it easier for developers to understand and utilize the serializers without diving deep into the implementation.
• Enhanced Maintainability: Facilitates better code maintenance by providing clear guidance on how each part of the class is intended to function.
• Increased Accessibility: Helps new contributors and users quickly get up to speed with the serialization utilities provided by the class.
