Gretel-synthetics

🐛 + ⚙️: Bug fixes and optimizations for the DGAN timeseries synthetic model!

**Full Changelog**: https://github.com/gretelai/gretel-synthetics/compare/v0.18.0...v0.18.1

⚙️ New model available! DoppelGANger for time series 📈 synthetic data generation!
⚙️ Updates to header clustering logic, added options for isolation batches based on average record length and field complexity
🐞 Bug fixes during record generation and for epsilon calculation when using DP
🔼 Updates to recommended core dependencies, specifically Python 3.9 and TensorFlow 2.8.

* 🚀 Adds a new `gretel_synthetics.utils` module containing stats and header clustering helpers. These modules should be installed via the new `utils` extra

pip install gretel-synthetics[utils]

* 🧹 Miscellaneous housekeeping and plumbing updates.

⚙️ Slight performance improvements for TensorFlow and memory footprint reductions

Enable early stopping for:

- Specified `min_delta` for the metric used between epochs
- Enable early stopping after a maximum run time
