BREAKING CHANGES
* The IntRangeExpr class now normalizes the steps of individual range components like "3-1:-2" to be positive like "1-3:2".

BREAKING CHANGES

* This release includes a few small changes to the public contract of `IntRangeExpr` and the `StepParameterSpaceIterator`. Review the changes to see if this affects your usage ([`9253018`](https://github.com/OpenJobDescription/openjd-model-for-python/commit/925301888ea997a7f4a0d4aae6638ed49b12a800)).
* Model classes migrated from Pydantic V1 to Pydantic V2, which is not backwards compatible. If you depend on Pydantic V1 APIs, consult this [guide](https://docs.pydantic.dev/latest/migration/) to migrate usage to Pydantic V2.([`0753a1b`](https://github.com/OpenJobDescription/openjd-model-for-python/pull/164/commits/0753a1bfe2ee2306f12af8b914a61116c81c5d4d)).
