Dict-typer

Support base types other than list and dicts in the root

* Use TypeDict with `pass` body for empty dicts
* Various other fixes

Each TypedDict would have the `Type` postfix, which is now dropped (but still optional in code)

Before
python
class RootItem0Type(TypedDict):
Foo: str


RootType = List[RootItem0Type]


After
python
class RootItem0(TypedDict):
Foo: str


Root = List[RootItem0]

Add support for rich output with the rich library
