Added
- Add form compression, use it in Python bindings and VDF client. Using compressed representation of quadratic forms reduces their serialized size from 130 to 100 bytes (for forms with 1024-bit discriminant). This shrinks the size of VDF outputs and VDF proofs. The form compression algorithm is based on ["Trustless Groups of Unknown Order with Hyperelliptic Curves"](https://eprint.iacr.org/2020/196) by Samuel Dobson, Steven D. Galbraith and Benjamin Smith.
- We now verify form size when deserializing.
- MacOS universal wheels to support MacOS ARM64 are built for Python 3.9.
Changed
- This is a breaking change from the 0.13.x series.
