Go back to 0BSD license

The goal has not changed and is still to enable this library for the
widest audience without restrictions. After reading many articles
regarding licensing, 0BSD seems like a more precise way to achieve this
goal.

- 0BSD is far from being as popular as MIT. That is its only drawback.
- The 0BSD license appears to have been recognized as an open-source
  license by major IT companies (no need to jump through legal hoops to
  use a 0BSD licensed library).
- 0BSD is short, simple and clear.
- 0BSD is unambiguous about attribution: attribution is not required.
