Put PlatformIO Boards In A Spreadsheet

The PlatformIO board listing is formatted for each platform group by a Python pretty-print library. The fields do not align if pasted into a file and it is not structured like CSV or Json for computer input. A speadsheet view might be optionally desirable so I provide a Lua script to do that.

--[[
  From PlatformIO boards.txt to boards.csv for spreadsheet view..
  
  The pio "boards" listing is not intended to be processed by a program.
  This Lua script fixes the irregular text format and outputs CSV.
  Usage:
  1. pio boards > btmp.txt
  2. Lua make_csv.lua
  3. Open boards.csv in a spreadsheet
