FSL-1.1-MIT(main branch and the 4.0 alpha pre-releases

The release people install today, PyCaret 3.3.2, is MIT-licensed and builds from the public repository. The maintainers have since relicensed the engine on the main branch to the Functional Source License (FSL-1.1-MIT), which forbids competing commercial use for two years after each release, starting with PyCaret 4.0. Only alpha builds of 4.0 have shipped, so the MIT release governs until 4.0 is released.

PyCaret's compare_models call trains and ranks every applicable model on the user's data and returns the best, so choosing among learners is done for the user. It sits with AutoGluon on that automation, though the user still drives each step with a function call.
