v1.2.0 - 2023-06-07

This release adds a parameter called verbose to the HMASynthesizer's initialization. Setting it to True will show progress bars during the fitting steps. Additionally, performance optimizations were made to the modeling and initialization of the HMASynthesizer.

Multiple changes were made to enhance constraints. The Range constraint was improved to be able to generate more accurate data when null values are provided. Constraints are also now validated against the data when running validate() on any synthesizer.

Finally, some warnings were resolved.
