Sébastien Crozet 134f433903 feat: solver improvements + release v0.29.0 (#876)
* feat: solver improvements

* feat: add function to get/set whether gyroscopic forces are enabled on a rigid-body

* chore: switch to released versions of parry and wide instead of local patches

* fix cargo doc

* chore: typo fixes

* chore: clippy fix

* Release v0.29.0

* chore: more clippy fixes

//! # Rapier
//!
//! Rapier is a set of two Rust crates `rapier2d` and `rapier3d` for efficient cross-platform
//! physics simulation. It target application include video games, animation, robotics, etc.
//!
//! Rapier has some unique features for collaborative applications:
//! - The ability to snapshot the state of the physics engine, and restore it later.
//! - The ability to run a perfectly deterministic simulation on different machine, as long as they
//! are compliant with the IEEE 754-2008 floating point standard.
//!
//! User documentation for Rapier is on [the official Rapier site](https://rapier.rs/docs/).
