The purpose of this PR is to demystify the process by which the DAP code is minified. In the repo's current state, it is not clear which tool is being used for minification or how that tool is configured. This PR adds an npm script that specifies how minification is to be performed - by the Terser library and with options described in minify_options.json. Terser is not what has been used up to now - currently the code is minified with the Google Closure Compiler. But the Closure Compiler is a Java app, which makes it awkward to use in our npm environment, and the minified file generated by Terser is the same size as the one generated by the Closure Compiler (29 KB), so we aren't losing any performance by switching tools.
One change resulting from this switch - the sourcemap file has been renamed from
Federated.js.mapto the more intuitive nameUniversal-Federated-Analytics-Min.js.map. I'll go through the wiki and update any references toFederated.js.map(I know the self-hosting instructions refer to this file, I'll look for any other places).
