depend on dioxus(and bevy)-maintained fork of stretch (taffy) (#4716)
# Objective DioxusLabs and Bevy have taken over maintaining what was our abandoned ui layout dependency [stretch](https://github.com/vislyhq/stretch). Dioxus' fork has had a lot of work done on it by @alice-i-cecile, @Weibye , @jkelleyrtp, @mockersf, @HackerFoo, @TimJentzsch and a dozen other contributors and now is in much better shape than stretch was. The updated crate is called taffy and is available on github [here](https://github.com/DioxusLabs/taffy) ([taffy](https://crates.io/crates/taffy) on crates.io). The goal of this PR is to replace stretch v0.3.2 with taffy v0.1.0. ## Solution I changed the bevy_ui Cargo.toml to depend on taffy instead of stretch and fixed all the errors rustc complained about. --- ## Changelog Changed bevy_ui layout dependency from stretch to taffy (the maintained fork of stretch). fixes #677 ## Migration Guide The public api of taffy is different from that of stretch so please advise me on what to do here @alice-i-cecile.
