This module is aimed at being a free of dependencies, performant and
complete UUID library for LuaJIT and ngx_lua.
Unlike FFI and C bindings, it does not depend on libuuid being available
in your system. On top of that, it performs **better** than most (all?)
of the generators it was benchmarked against, FFI bindings included.
Finally, it provides additional features such as UUID v3/v4 generation and
UUID validation.
