AmpForm-DPD 0.2.0

✨ New features

• Describe initial and final state particles with State class (#116)
• Handle equal particles in final state (#108)

⚠️ Enhancements and optimizations

• Group decay node in LaTeX rendering of ThreeBodyDecayChains (#114)

⚠️ API changes

• Initial and final states in ThreeBodyDecayChains are now defined with a State class (#116). This should affect the API too much, as it inherits from Particle, which was used initially for initial and final state particles.

📝 Documentation

• Added $\Xi_b^- \to p K^- K^-$ example notebook (#117) for testing #108
• Host documentation on Read the Docs (#119 and #122)
