  This site uses the library unmodified, as separate files that the HEIC
  converters load only when you add a HEIC or HEIF file (see
  /assets/js/image-decode.js). You may replace libheif.js and libheif.wasm
  with your own build of the same interface, or a modified version, and the
  tools will load it instead.
