This is the first stable release of ipywidgets-jsonschema.

The project allows to create form objects from existing schemas that follow the JSONSchema specification. Form objects display as widgets based on ipywidgets in Jupyter. The current state of the widgets can be read and manipulated through the `data` property of the form object.

Introduces a bunch of fixes that make generated widgets simpler and display better. Additionally, setuptools_scm is introduced.

Fixup to conditional properties being introduced in v0.11.0: The same property can now be introduced by multiple conditional subschemas.

Implement partial support for 'if'-'then' conditionals in schemas.
