Patch: closes: #3 - Also makes schema more explicit

* use already loaded SCHEMA from kaiba.schema instead of reading file in tests
* Make sure that mappings is required based on if 'default' is present or not, and both should of course have 'name' required
* Make sure we have at least 1 item in mappings if default is not provided
* Add patch entry in CHANGELOG
* bump patch in pyproject
