chore: Bump faer to v23.2 (#182)

* Bump faer to 23.2

Faer is finally back in active development!

* Use traits from faer over faer_traits

* WASM support

Manually including the `wasm_js` feature of the `getrandom` crate

* Add rustflags

* Trying again

* Add the platform crate

* Bump faer-traits

* Attempt to fix wasm target with latest faer

This excludes rayon as a feature in faer when the target is wasm

* Avoid pulling faer from workspace

* match faer versions

* move common default features to workspace
