Bezier-rs: Subpath offset and bezier offset improvements (#1039)

Browse Source 
* Added subpath offset

* Enhanced offset to produce smooth curves

* Lots of outline bugfixes

* Fixed failing unit tests

* Added subpath outline

* Refactor bezier offset and outline to return Subpaths

* Fix outline bug due to smooth joining and removed reduce optimization that causes jumping approximations

* Bugfix when subpath angle is acute but doesn't intersect

* Stylistic changes per review

* Stylistic changes per review and updated doc comments
