/**
* Writes compressed C arrays of data files (web interface)
* How to use it?
*
* 1) Install Node 11+ and npm
* 2) npm install
* 3) npm run build
*
* If you change data folder often, you can run it in monitoring mode (it will recompile and update *.h on every file change)
*
* > npm run dev
*
* How it works?
*
* It uses NodeJS packages to inline, minify and GZIP files. See writeHtmlGzipped and writeChunks invocations at the bottom of the page.
