fix(build): use common header and Babel preset (#52)

See visjs/vis-dev-utils#5.

As in other projects has already been done:
- There should be no more prototype polution.
- Uglify was replaced by Terser (Uglify was removing the header).
- The build in banner was used instead of the plugin (the plugin was
messing up source maps which now work).
- Some unused dependencies were removed.
