Origin

Based on initial the work of AnthonyDiGirolamo from AnthonyDiGirolamo/lua-teensyduino:

This is Lua 5.1.5 with the following patches:

1. Lua Tiny RAM (LTR)

   This is used in eLua and nodemcu

2. Lua Compact Debug (LCD)

   Original patch can be found here: https://github.com/TerryE/lua-5.1/commits/master
