Lua (5.3) Language addition (#4804) * 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
