What's changed?

Highlights

• ✅ Newton-Raphson calculation method for state estimation (see the documentation).
• ✅ Optional separate sigmas for active power and reactive power for power sensors (see the documentation).
• ✅ Get the batch size of an update data set (see the API reference).
• 💥 Multiple bug fixes (see e.g. #462 and #477 ).
• 🚀 Improvements and fixes to documentation.
• 🎉 Various improvements to the internal implementation and compiler support.
• 🎉 The licenses of source and data files were updated.
