Bezier-rs: Add parametric evaluate and line intersect to subpath (#852)

Browse Source 
* add slider to subpath component + change evaluate to take an enum

Co-authored-by: Rob Nadal <RobNadal@users.noreply.github.com>

wip - add intersect to subpath, TODO fix bug

Co-authored-by: Rob Nadal <RobNadal@users.noreply.github.com>

add unit tests to subpath intersections

stress, testing

Co-authored-by: Hannah Li <hannahli2010@gmail.com>

* add parametric eval impl to subpath

* add line intersection to subpath

* Uncomment and #[ignore] disabled tests

* Reorder a few imports

* change subpath:eval slider to radio button

* fixed bug with solve_cubic, fixed unit tests, improved intersection accuracy

* fix failing test
