v1.0.0

• Separate crates cwdemangle and cwdemangle-bin.
• cwdemangle (library) now has no dependencies and is no_std.
• Add --mw-extensions to support Metrowerks extension types (__int128, __vec2x32float__, etc.). Disabled by default since they conflict with template argument literals and can't always be demangled correctly.
• Fix issues with symbols in C++ classes/namespaces that contain double underscores.
