* Support custom parameter types
While most CLI parameters are strings, ints, etc, we sometimes need custom
types.
Currently typer has no support for it (See #77), and while there are a few hacks, the
likely solution is to add a 'str' argument and parse it inside the main function.
This PR adds support for custom types in 3 different ways:
- Manually specifying a `click_type`
- Manually specifying a `parse` function
- Using a Callable type annotation (It is very common for types to have a string constructor, like `int("1")`)
* Document how to parse custom objects with Typer.
Typer supports parsing of cutom types with:
- A user provided parser class
- A click custom type parser
* 🎨 [pre-commit.ci] Auto format from pre-commit.com hooks
* 📝 Tweak and simplify docs
* ✅ Tweak tests to run scripts and remove pragma: nocover in examples
* 📝 Tweak examples for docs, add types and remove # pragma: nocover
* ♻️ Tweak implementation checking for parser and Click type
