[Mjboothaus]

Adds mojo-ini v0.2.2 - INI parser and writer for Mojo with Python configparser compatibility.

Version update: v0.2.1 → v0.2.2 includes pre-commit whitespace fixes.

Resubmission after closing PR #194 following the modular-community standards guide.

Package features:

• Native INI parsing and writing in Mojo with zero Python dependencies
• Python configparser compatibility for easy migration
• Classic INI syntax with sections [Section] and key=value pairs
• Multiline values with indented continuation (like Python configparser)
• Comment support (# and ; prefixes)
• Case-sensitive keys and sections
• Clean public API: parse(), to_ini(), parse_file(), write_file()
• Built as .mojopkg for better import experience
• 37 tests passing (100% core functionality)

Use case: Perfect for configuration files, application settings, CI/CD configs, and any Mojo application needing INI format support with Python compatibility.
