chore!: only include ESM in the npm package (#266)

Get rid of the UMD bundle: not pratical, not minimified so not ready for
production, nor for reuse.
This lets remove the webpack build which was not used anymore.

- core build: everything is done with tsc and simplify pack
- remove webpack configuration
- Move typedoc in the package where it is used (make it easier to detect
usage)
- remove unused dependencies: 
  - better-docs (use typedoc instead)
  - webpack loaders (css, file, style, url)
  - babel
  - circular-dependency-plugin (webpack plugin)
  - webpack
  - cross-env
- core build: tsc only

BREAKING CHANGE: the UMD bundle is no more provided in the npm package
