Raise legible error when trying to emit TOML with null values #183

Open kislyuk opened 4 months ago

kislyuk commented 4 months ago

TOML does not support null values (not sure how that makes any sense, but apparently it never will: https://github.com/toml-lang/toml/issues/30)

We currently raise the following error when encountering them: tomlkit.items._ConvertError: Invalid type <class 'NoneType'>

Come up with a more legible error that makes it more obvious what's going on.
