chore: simplify parsing

[EvanBacon]

• Removes comment parsing which we discard anyways.
• Uses a better list of binary characters to wrap.

Testing Improvements:

• Introduced a new test suite in src/json/__tests__/unicode-edge-cases.test.ts to validate Unicode escape sequences, NextStep character mappings, octal escapes, string parsing edge cases, data literals, and round-trip preservation of .pbxproj files.

Parser Enhancements:

• Implemented a complete NextStep Unicode mapping table in src/json/parser/identifiers.ts to ensure compatibility with Xcode's specific character mappings.
• Refined the stripQuotes function to handle complex escape sequences, including Unicode, octal, and control characters, while ensuring accurate parsing of quoted strings.
• Simplified the regex for matching quoted strings in matchQuotedString and improved handling of data literals in matchData.
• Removed custom handling of comments in the parser and streamlined the PbxprojParser class for better maintainability. [1] [2]
