/// Some files have some slight edits made to ensure the gbr -> rust -> gbr works
/// correctly. The changes do not change the meaning of the file.
/// The edited files are in the `edited` folder so they can be compared to the originals.
/// For example, when gerber-types serializes decimals (not co-ordinates), trailing 0's are removed.
