Lua 5.4 support?

[flozano]

In luarocks install, I am getting:

$ luarocks install --tree lua_modules https://raw.githubusercontent.com/srdgame/librs232/master/rockspecs/rs232-scm-0.rockspec
Missing dependencies for rs232 scm-0:
   lua >= 5.1, < 5.4 (not installed)

rs232 scm-0 depends on lua >= 5.1, < 5.4 (not installed)

Error: Could not satisfy dependency lua >= 5.1, < 5.4: Rock lua 5.4-1 is already provided by VM or via 'rocks_provided' in the config file.
