PatientLevelPrediction 6.4.0
======================
- Official maintainer updated to Egill Fridgeirsson
- Feature: Added experimental imputation methods
    * Simple imputation using median or mean
    * Iterative imputation by chained equations using predictive mean matchin
- Feature: Added more feature engineering methods to deal with rare features and
 normalization of numerical features
    * Min/Max normalization
    * Robust normalization which normalizes by the interquartile range and
optionally squashes the features to a range -3 to 3
- Feature: Added existingSplit settings where users can split data bases on an 
existing split
- Feature: Added a net benefit plot `plotNetBenefit`
- Feature: Added timings that are printed to the log to most functions in the pipeline
- Feature: Now a model trained with `scikit-learn` in python can be converted with 
`createSklearnModel` and used to predict on new data with the package
- Feature: Added a convenience function `getEunomiaPlpData` to get some data
in one line.
- Docs: Added a new GIS example to the docs (thanks @jshoughtaling)
- Docs: All exported functions (about 120) now have runnable examples. All examples
are now conditinally executed if required. Shiny examples only executed in 
interactive sessions, examples using packages in suggests only executed if 
they are installed and so on.
- Docs: Fixed linting errors and R codestyle in docs to conform to HADES style
- Docs: Remove links to pdf's, point to website instead.
- Docs: Fix broken links in Readme and BuildingPredictiveModels vignette
- Internal: Added support for coming `duckdb` backed `Andromeda`
    * Only create indexes for `sqlite` backed `Andromeda`
- Internal: Removed the old simulationProfile and added a new one based on Eunomia
    * This will allow us to quickly simulate small datasets for examples
    * Manually specified an outcome model tailored to `Eunomia`
- Internal: Went through all tests and put `skip_if_offline` or `skip_if_not_installed`
where appropriate. Tests using `Eunomia` need internet and tests using any 
suggest packages need `skip_if_not_installed`. Put `skip_on_cran` for all 
tests requiring python
- Internal: Cleaned up dependencies. Moved what could be moved to suggest and put behind
a `rlang::check_installed` flag. This means the installation is much lighter if 
only using the basic functionality of the package, e.g. develop a model using 
Cyclops.
- CI: Use UV for python management on github actions and upgrade ubuntu version to 
24.04
- CI: Added an action to detect broken links in repo
