Lus 1.0.0

Lus 1.0.0 is the first major release of the language.

This changelog denotes differences between Lus and Lua 5.5 RC 2. Lua 5.5 most (in)famously introduces the global assignment statement; it is not a Lus-specific feature.

• Added table deconstruction with from assignment.
• Added scoped assignments in if/elseif conditionals.
• Added catch expression for error handling in expressions.
• Added optional chaining with the ? suffix operator.
• Added first-class enums with the enum keyword.
• Added os.platform function that returns the platform name.
• Added support for WebAssembly builds.
• Added pre-built test suites in four harnesses.
• Removed pcall and xpcall in favor of catch.
• Upgraded the build system from make to meson.
