Major release since there are breaking changes on how `SlotValue` are represented.
- ✨ Added `pytlas.testing` namespace containing some utilities to easily unit test your skills, see [the documentation](https://pytlas.readthedocs.io/en/latest/writing_skills/testing.html) for more informations
- 💥 `SlotValue` value now not always returns a `str`. The `value` property will now contains a more meaningful python representation of the slot (`dateutil.relativedelta` for durations, `pytlas.interpreters.slot.UnitValue` for AmountOfMoney and Temperature, `float` between `0` and `1` for percentages, `datetime.datetime` for InstantTime, tuple of `datetime.datetime` for date range and `str` for anything else). This make the developer stuff easier when retrieving slot with `request.intent.slot('my_slot').first().value`
- ♻️ `SkillData` is now called `Meta`
