* feat: support segment midpoints in line editor
* fix tests
* midpoints working in bezier curve
* midpoint working with non zero roughness
* calculate beizer curve control points for points >2
* unnecessary rerender
* don't show phantom points inside editor for short segments
* don't show phantom points for small curves
* improve the algo for plotting midpoints on bezier curve by taking arc lengths and doing binary search
* fix tests finally
* fix naming
* cache editor midpoints
* clear midpoint cache when undo
* fix caching
* calculate index properly when not all segments have midpoints
* make sure correct element version is fetched from cache
* chore
* fix
* direct comparison for equal points
* create arePointsEqual util
* upate name
* don't update cache except inside getter
* don't compute midpoints outside editor unless 2pointer lines
* update cache to object and burst when Zoom updated as well
* early return if midpoints not present outside editor
* don't early return
* cleanup
* Add specs
* fix
