This adds basic support for different Lua versions.
For Lua 5.2 and Lua 5.3, both the Bit32 and Compat53 Lua modules must be
installed for it to work. You can typically get these on Linux using
apt install lua-compat53 lua-bit32
For Lua 5.4, it should work as is, as it is a clean superset of Lua 5.3,
which is what the original Lua Flatbuffers supported.
LuaJIT as installed by apt doesn't include the COMPAT mode for using
Lua5.2 features. So this change just makes the flatbuffer code use a
common implementation.
* [Lua] Add LuaJIT support
Here is the output of LuaTest.sh:

* [Lua] Better usage description
* update according to the review
The packing/unpacking steps for Boolean values was failing because the
code expected numerical values. I overrode the functions for the Boolean
metatable to account for this. I also had to exclude the Boolean
metatable from the GenerateTypes helper function, as that was overriding
the Pack/Unpack functions defined in its metatable.
Added Linux bash script to run Lua tests from the command line.
Bug: google/flatbuffers#5379
Tested: Added Lua tests that were failing and are now fixed with the
code changes.
Fixed a bug that prevented vtable reuse during buffer construction in the lua library.
Also fixed a bug in vtable equality check that was revealed after the first fix.
* starting Lua port of python implmention. Syncing commit
* Bulk of Lua module port from Python done. Not tested, only static analysis. Need to work on binary strings. Started work on flatc lua code generation
* Fixed all the basic errors to produced a binary output from the builder, don't know if it is generated correctly, but it contains data, so that must be good
* fixed binary set command that was extending the array improperly
* continued improvement
* Moved lua submodules down a directory so their names don't clash with potential other modules. Added compat module to provide Lua versioning logic
* Successful sample port from Python
* working on testing Lua code with formal tests
* continued to work on tests and fixes to code to make tests pass
* Added reading buffer test
* Changed binaryarray implmentation to use a temporary table for storing data, and then serialize it to a string when requested. This double the rate of building flatbuffers compared to the string approach.
* Didn't need encode module as it just added another layer of indirection that isn't need
* profiled reading buffers, optimizations to increase read performance of monster data to ~7 monster / millisecond
* Writing profiler improvments. Get about
~2 monsters/millisecond building rate
* removed Numpy generation from Lua (came from the Python port)
* math.pow is deprecated in Lua 5.3, so changed to ^ notation. Also added .bat script for starting Lua tests
* adding results of generate_code.bat
* simple edits for code review in PR.
* There was a buffer overflow in inserting the keywords into the unorder set for both the Lua and Python code gens. Changed insertion to use iterators.
* fixed spacing issue
* basic documenation/tutorial updates. Updated sample_binary.lua to reflect the tutorial better
* removed windows-specific build step in Lua tests
