Add Accessor control

[FlickerSoul]

This pull request introduces a new way to control access levels for generated parsing and printing extensions in the @ParseStruct and @ParseEnum macros, allowing users to specify custom access modifiers.

Pull request overview

This pull request introduces access control for generated parsing and printing extensions in the @ParseStruct and @ParseEnum macros. Users can now specify custom access modifiers (public, package, internal, fileprivate, private, or follow) via parsingAccessor and printingAccessor parameters, with .follow as the default to match the declaration's access level.

Key changes:

• Added ExtensionAccessor enum in BinaryParseKitCommons to represent access levels
• Implemented extractAccessor function and MacroAccessorVisitor for parsing and validating accessor arguments
• Updated @ParseStruct and @ParseEnum macro signatures to accept accessor parameters
• Added comprehensive test coverage for accessor functionality including validation of invalid accessors
