* Fixed a bug in the Lua 5.1 bytecode pattern
Lua 5.1 bytecode upvalue fields were incorrectly defined as a `Vector<u32>` instead of `Vector<LuaString>`.
* Fixed another bug in the lua 5.1 bytecode pattern
Lua 5.1 bytecode string sizes were incorrectly parsed as a 64-bit integer, instead of a 32-bit integer.
* Updated the Lua 5.1 bytecode pattern for 32-bit compilers.
Updated the pattern to allow for 32-bit and 64-bit integers for the size of the string length field.
