Move source to folder & Replace standardx with eslint & Update .npmig…

…nore (#321)

* Move all source code files to a new `src` folder to improve structure
of the repo.
* Replace `standardx` linter with `eslint` using the standard rules.
This allows more flexibility and works around the fact, that `standardx`
seems outdated regarding our eslint version.
* Update .npmignore to exclude more development related files and
therefore decrease package size by a few kilobytes.
