Refactor IPropertyBagValue into Type-Specific Derived Classes

[adydecki]

As part of our ongoing efforts to enhance the XPing365 project’s codebase, this issue proposes a significant refactoring of the IPropertyBagValue interface. The goal is to create four new derived classes, each tailored to handle a specific data type. This change aims to streamline type management and improve the clarity and maintainability of our code.

The new classes to be introduced are:

• StringPropertyBagValue for handling single string values.
• StringArrayPropertyBagValue for managing arrays of strings.
• ByteArrayPropertyBagValue for byte array data.
• DictionaryOfStringsPropertyBagValue for dictionaries with string keys and values.

Expected Outcomes:

• Clear separation of concerns where each class is responsible for a single type.
• Simplified code paths for operations like serialization and deserialization.
• Enhanced type safety and reduced risk of runtime type errors.

Implementation Notes:

• Current PropertyBagValue should became an abstract class and renamed to SerializedPropertyBagValue.
• Each new class should implement the SerializedPropertyBagValue abstract class.
• Include unit tests to cover the new functionality and confirm that existing features remain unaffected.
• Update the documentation to reflect the new class structure.

This refactoring is a step towards a more robust and type-safe architecture
