What's Changed
* fix plot_ppc with components for fixed parameters by renecotyfanboy in https://github.com/renecotyfanboy/jaxspec/pull/219
* patching DiskBB by renecotyfanboy in https://github.com/renecotyfanboy/jaxspec/pull/220
* Migrate to uv by renecotyfanboy in https://github.com/renecotyfanboy/jaxspec/pull/225


**Full Changelog**: https://github.com/renecotyfanboy/jaxspec/compare/v0.2.1...v0.2.2

Upgrades

- Better documentation on how to mock data without explicit observation
- `fakeit_for_multiple_parameters` has been optimized to explicitly prevent the replication of response matrix, easing folding for multiple parameters at once without blowing up memory
- `prior_predictive_coverage` should use multiple cores now
- Internal cleaning : we do not depend explicitly on the Heacit dataset but rather download what is needed on the fly

Bug Fixes

- Fix `tbpcf` and `FDcut` models that were not fully ported after the internal rework of `jaxspec`
- Fix `Agauss`, `Zagauss`, `Zgauss` which were in a similar situation


**Full Changelog**: https://github.com/renecotyfanboy/jaxspec/compare/v0.2.0...v0.2.1

This new version brings a brand-new backend for the `jaxspec` model building tool. We are switching from `haiku` (which is now in maintenance mode) to `nnx` to handle the parameters in `JAX`. It brings some new breaking changes, but will help a lot for future maintenance.

Upgrades
* Background model scaling has been fixed, there was an issue because the scaling factor was applied after folding while it should be before.
* `plot_ppc` can now display multiple components in the model, see [here](https://jaxspec.readthedocs.io/en/latest/examples/fitting_example/)
* Codebase and documentation were cleaned a bit

Breaking changes
* Model parameters are now all lower case and underscore use is forbidden for now. If you used components such as `tbabs`, be sure to change `N_H` to `nh`
* Custom model components should be built using `nnx`. It changes a bit when compared to `haiku`, and has been updated accordingly in the [documentation](https://jaxspec.readthedocs.io/en/latest/examples/build_model/#build-a-custom-component)
