A new tool is now included, "gcodecheck". This tool will perform sanity checks on a gcode file, and it will create a "fingerprint" of the gcode. This fingerprint will be compared next time this tool is run and key differences flagged. This allows for a CI/CD kind of workflow for gcode generation (e.g. the tools in this repo, but the gcodecheck tool is not specific to anything in this repo and should also work with Carbide Create and other CAM tools)
