Implement function that projects to a Bezier curve (#688)

* UI section for the projection function

* added bezier project impl

* Fix project function and add test for it

* Search method

* Re-use comptued distances

* Update comments

* rebase project changes

* clean up tests and library code

* use built-in functions and destructure syntax

* Remove redundant project implementation

* Fix typo, add lut size as parameter and add constant

* address comments
