New nodes: Resample Points, Spline from Points (#1226)

Browse Source 
* Create node (no implementation)

* Resampling - WIP

* use bezier::from_linear_dvec2

* Use from anchors instead of Bezier

* Tidy up anchor collection & subpath creation

* Add Spline from Points node (not implemented)

* Add spline from points node implementation

* Update resampling

* Update minimum density 0.01 -> 1.0

* Add a way to create a custom vector network

* Add spline from points node to spline tool

* Fix crash when no points

* Add anchor method to subpath

* Exact start and end point

* Fix compile errors from rebase

* Fix spline tool

* Rename 'Density' to 'Spacing'

* Fix transforms

* Only close subpaths with >1 anchor

* Fix compile

* Fix compile error

* Fix from points with many subpaths

* Fix new_cubic_spline crash with one point

* Rename to resample as polyline

* Fix div zero

* Fix missing file

* Fix resample

* Rename to resample points
