Announcing mlua 0.8.0-beta with Roblox Luau support

Hello,

I'm glad to announce first mlua version 0.8.0-beta.1 with Roblox Luau support.

mlua provides unified high level interface to all Lua versions (5.1-5.4) including LuaJIT and now Luau with simple switch between them using feature flags.

Luau support works in vendored only mode (no vendored feature flag required) and provides all key mlua features including async/await and userdata values (by emulating them).

Also mlua implements require function to load Luau modules since it's missed in the standard implementation. Only notable missing functionality is readonly tables and sandboxing which will be supported in next versions.
