node-ampproject-remapping binary package in Ubuntu Lunar amd64

 Remapping allows one to take the sourcemaps generated through transforming
 code and "remap" them to the original source locations. Think "minified code,
 transformed with babel and bundled with webpack", all pointing to the correct
 location in your original source code.
 .
 With remapping, none of source code transformations need to be aware of the
 input's sourcemap, they only need to generate an output sourcemap. This
 greatly simplifies building custom transformations.
