Replace Dice with slince/di

Dice is okay but the code is showing its age (very dynamic),
it is not very actively developed and lacks PSR-11 support.

Looking at other options on Packagist, skipping obviously abandoned
or associated with the facade-infested framework:

- https://github.com/nette/di
  😡 container generator
  😡 too featureful
- https://github.com/symfony/dependency-injection
  🙂 native PSR-11
  😡 promotes configuration
- https://github.com/PHP-DI/PHP-DI
  🙂 nice docs
  😡 also too featureful
- https://github.com/auraphp/Aura.Di
  😡 verbose API
- https://github.com/ray-di/Ray.Di
  🙂 nice docs
  😡 “enterprise” API
- https://github.com/slince/di
  🙂 native PSR-11
  🙂 nice API
  😡 few unneeded features (aliases, parameters, tags)
- https://github.com/thephpleague/container
  🙂 native PSR-11
  🙂 nice API
  🙂 nice docs
  😡 even more unneeded features (inflectors)

After reviewing all of the above, I selected Slince’s DI library.
There were some bugs but they were quickly addressed upstream.
