Add byteops-milo module for Eclipse Milo unsigned types

[kevinherron]

What problem(s) was I solving?

Projects using Eclipse Milo's OPC UA stack have their own unsigned types (UByte, UShort, UInteger, ULong) in org.eclipse.milo.opcua.stack.core.types.builtin.unsigned. Currently, there's no convenient way to read/write these types using byteops - users would need to manually convert between primitive types and Milo's unsigned types.

What user-facing changes did I ship?

Added a new byteops-milo module that provides MiloByteOps<T> - a wrapper class for working with Eclipse Milo's unsigned types. This follows the same pattern as the existing byteops-unsigned module (which wraps jOOU types).

New API methods:

• getUByte / setUByte - read/write UByte values
• getUShort / setUShort - read/write UShort values
• getUInt / setUInt - read/write UInteger values
• getULong / setULong - read/write ULong values
• Array variants for all of the above

How I implemented it

• Created new byteops-milo Maven module with dependency on org.eclipse.milo:milo-stack-core:1.0.8
• Implemented MiloByteOps<T> using the delegation pattern (same as UnsignedByteOps<T>)
• The class implements ByteOps<T> and delegates all standard operations to the wrapped instance
• Added @NullMarked package annotation for nullability consistency with the rest of the project

How to verify it

Automated

• mvn clean package passes
• All tests pass (16 new tests in MiloByteOpsTest)

Manual Testing

• Verify module appears in IDE as recognized Maven module
• Verify Milo dependency is resolved and unsigned type classes are available

Description for the changelog

Add byteops-milo module providing MiloByteOps<T> wrapper for Eclipse Milo unsigned types.
