Lua (5.1) file support

[ImanCol]

N64 NSO uses compiled Lua 5.1 files. The header is somewhat different as is the structure and the decompilers do not generate the exact files. Could you add support for these files so that they can be edited (decompiled) and saved (compiled)? core.zip

Use unluac.jar but not all of them generate correct format, also use decompiler.com but it gives error on big files and format is still wrong for most lua files
