Improve exceptions for missing config values
Hi, It's me again. Amazing progress on the project!
It would be nice if missing config values had a better exception.
Currently the exception looks like this: typed_settings.exceptions.InvalidValueError: __init__() missing 1 required positional argument: 'option_two'
But it would probably make more sense to say something like: MissingConfigVauleError: 'option_two' is not set
